etal bar grating can be defined as a seriesof metal bars positioned vertically, placed

an equal distance apart and joined by crossmembers to form a rectangular or reticuline pat-tern. Typically manufactured from mild carbonsteel, 6000 series aluminum and 300 series stain-less steels, bar gratings are also available in spe-cialty metal alloys to suit nearly any application.

BEARING BARS – The vertically positioned barsare designated as the bbeeaarriinngg bbaarrss.. These barsrange in size from 3/4" x 1/8" for light pedestri-an traffic to 7" x 1/2" for extreme vehicularloads. Typically, the spacing of the bearing barsis indicated in sixteenths of an inch, measuredfrom the center of one bar to the center of theadjacent bar. This center-to-center or oonn cceenntteerrspacing ranges from 7/16" to 19/16" (1-3/16") onstandard grating products. Standard gratingsare also available with wider spacingsproviding even greater openarea, but should not bespecified without

consulting the manufacturer. Heavy Dutygrating products are commonly manufac-tured with bearing bar spacings rangingfrom 15/16" to 38/16" (2-3/8") on center.

CROSS BARS – The bars used to securethe position of the bearing bars are com-monly designated as the ccrroossss bbaarrss.. Crossbar profiles vary according to the method ofassembly and material selected. As withbearing bars, cross bar spacing is measuredas oonn cceenntteerr spacing. The customary crossbar spacing is 4" on center. On special order,2" on center and other special spacings arealso available.

INTRODUCTION

SWAGED PRESSURE LOCKEDCross bars are inserted into pre-punched holes in the bearingbars and hydraulically swagedto lock the bars in place. Mosteffective for the manufacture ofaluminum, stainless steel, andclose mesh gratings.

DOVETAIL PRESSURE LOCKEDAssembled by insertingpunched bearing and cross barsinto an "eggcrate" configurationand deforming the cross barsunder hydraulic pressure.Excellent for the manufactureof architectural gratings.

RIVETED GRATINGBearing bars are permanentlyriveted to reticulated cross barsto form our most rigid anddurable products. Extremelywell suited to absorb shockand impact loads from cartand dolley traffic.

SPAN

WIDTH

UNSUPPORTED SPAN

roper specification of bar gratings includes adetermination of load conditions, effective

unsupported clear span, flooring surface, trimand finish. Appropriate consideration of theseelements plus any features unique to their partic-ular application will allow the specifying authori-ty to select products that will provide years ofcontinuing service.

SPAN – In grating nomenclature, ssppaann servesa dual role in defining two significant features.First, uunnssuuppppoorrtteedd ssppaann indicates the clear dis-tance between effective points of support for thegrating. Once the specifier has established thedesign load and acceptable deflection criteria,grating selection will be dictated by determiningthe maximum unsupported span and consultingthe load tables on the pages that follow. Secondly,ssppaann indicates the overall finished length of thegrating panels (parallel to the bearing bars) asthey are supplied to the customer.

WIDTH – The overall dimension of the gratingpanel measured perpendicular to the bearing barspan is designated as the panel wwiiddtthh.Commonly manufactured and stocked in 24" and36" nominal widths, grating panels can easily besupplied in a variety of widths to suit the needsof any application. For non-stock widths, consultthe Panel Width Chart on page 17 of this cata-log. Additionally, custom widths can be shop fab-ricated to hold any specific tolerance.

SERRATED SURFACE – The excellent drainageand self-cleaning characteristics of plain surfacegrating make it suitable for the majority of appli-cations. In the presence of materials which could

cause the top surface of the bars to become slip-pery, the optional sseerrrraatteedd surface should beconsidered. When serrated surfaces are specified,the bearing bar depth must be increased 1/4"greater than the sizes shown in the load tablesand selection guides to provide the equivalentstrength of non-serrated bars.

BANDING – To enhance architectural appear-ance or to provide additional transverse stiffness,the open ends of the grating panels can be bbaanndd--eedd. This is achieved by welding a flatbar, similarin size to the bearing bars, to the cut ends of thegrating panel. Banding can reduce impact stressesby transferring loads to adjacent bars that are notdirectly subjected to service loads. Trim bandingshould always be considered when the gratingpanels are designed to be removable on even aninfrequent basis. Additionally, banding shouldalways be specified when the ends of the bearingbars are unsupported or the grating is designedto service vehicular loads. Further bandingdescriptions and welding standards can be foundon page 17 of this catalog.

FINISHES – Steel grating products are usuallyshipped with one of three standard finishes, baresteel, painted with one coat of the manufacturersred or black paint, or hot dip galvanized after fab-rication in accordance with ASTM Standard A-123.Aluminum products are commonly supplied asmill finished, but are also available with optionalanodized finishes. Stainless steel products as pro-duced typically require secondary finishing suchas chemical cleaning, abrasive blasting or electro-polishing. All of our grating products can addi-

tionally be supplied with specialty custom finishessuch as enamel or epoxy coatings. When consider-ing such finishes, careful evaluation of the speci-fied material and consultation with the coatingmanufacturer is essential.

WELDED STEEL GRATING

hen selecting a bar grating product, consider Welded Steel Grating first. Usuallyour most economical products, they provide a comfortable walking surface

with nearly 80 percent open area. This, combined with the positive welded crossbar/bearing bar intersection, make these products our most popular. Manufacturedfrom ASTM A-1011 carbon steel, welded gratings are recommended for nearly allindustrial flooring applications.

To specify welded steel grating, first specify the ttyyppee of grating from the adjacenttable. In the instance of standard welded grating, the "WW" indicates the assembly ofthe grating shall be Welded construction, the ""1199"" indicates that the bearing barsshall be 19/16's (1-3/16) inches on center, and the ""44"" indicates that the cross barsshall be spaced at 4 inches on center. Following selection of the ttyyppee of grating, con-sult the load table below to select the appropriate bearing bar size for the loads andspans to be serviced. Proper designation for standard welded grating with 1" x 3/16"bearing bars is indicated WW--1199--44 11"" xx 33//1166"".

Bearing bars spaced at 1-3/16" oncenter and close spaced cross bars at2" on center. Preferred for short spansand where small wheeled carts mustsmoothly pass over the grating.

Bearing bars spaced at 15/16“ on centerwith cross bars at 4" on center. Providesadditional floor surface area andincreases load capacity by 26% whencompared to standard spaced products.

Bearing bars spaced at 15/16” oncenter and close spaced cross bars at2" on center. Yields the dualadvantage of closer spaced bearingbars and cross bars.

The bar spacings on types W-11-4and W-11-2 both conform with therigid provisions of the Americanswith Disabilities Act. Whenspecifying gratings to comply withADA requirements, it is critical tospecify 3/16” thick bearing bars that span "perpendicular to the normal flow of traffic."

luminum grating products are light in weight, resistant to atmospheric corrosion, non-sparking and offer an attractive appearance. These characteristics make aluminum grating

especially suitable for water and sewage treatment facilities, marine environments, food process-ing and petro-chemical installations. Manufactured from 6061 and 6063 alloys, the most popularand economical method of assembly for aluminum gratings is pressure locking by the swagingprocess. This versatile manufacturing system allows us to offer three distinct profiles: StandardRectangular Bar, Flush-Top Rectangular Bar and I-bar. Each profile is illustrated below.

To specify Grating Pacific Swaged Aluminum Grating, the type of grating is indicated by des-ignating one of the three profiles shown combined with the bearing bar/cross bar spacings illus-trated in the table. Following selection of the type of grating, consult the load table below toselect the appropriate bearing bar size for the loads and spans to be served.

ISOMETRIC SWAGED INTERSECTION

S W A G E D P R E S S U R E L O C K E D G R AT I N G SPressure Locked Gratings manufactured by swaging are designated by the

profile ""PPSS.."" These products are assembled by inserting hollow tube cross barsinto pre-punched holes in the bearing bars and then swaging the cross bars(similar to the aluminum gratings found on page 4). This permanently locks theentire cross bar/bearing bar intersection within the interior of the bearing bar.

D O V E TA I L P R E S S U R E L O C K E D G R AT I N G SPressure Locked Gratings manufactured with deep rectangular cross bars are

identified as dovetail pressure locked and are designated by the profile ""PPDD..""These products are assembled by pre-punching both the bearing bars and crossbars, aligning the bars in an eegggg--ccrraattee manner, and deforming the cross bar intothe dovetail slot in the bearing bar under intense hydraulic pressure.

C U S T O M B E A R I N G B A R S PA C I N G SThe Dovetail Pressure Locked method of manufacturing is particularly flexi-

ble in that it allows for the production of gratings with custom bearing bar spac-ings. Small quantities can easily be manufactured to suit the precise needs ofmost applications. To specify non-standard spacings, simply insert the desiredbearing bar center-to-center spacing (in sixteenths of one inch) in lieu of thestandard spacings shown in the table above (note that 4" and 2" cross bars cen-ters should be maintained).

EXAMPLE: PD-8-4 FOR GRATING WITH BEARING BARS AT 1/2" ON CENTER

B E A R I N G B A R S E L E C T I O N & L OA D TA B L E SThe bearing bar sizes offered for pressure locked gratings are common to

those in welded steel, swaged aluminum and stainless steel gratings. In that thesizes and spacings of the bearing bars are consistent with these products, theload tables are similarly interchangeable. Load tables for pressure locked gratingscan be found on the following pages:

rating Pacific offers two distinct types of Pressure Locked Gratings which are iden-

tified by their method of assembly.Manufactured without the introduction of heator riveting, these gratings provide a finishedproduct with attractive architectural lines. Thispleasing appearance makes Pressure Locked

Gratings ideal candidates for architectural andornamental applications such as grilles, screensand fences. Additionally, pressure locked meth-ods of manufacturing allow for the productionof close mesh gratings with minimal open area.Pressure Locked Gratings with bearing barsspaced at 11/16" and 7/16" on center conform

with the rigid spacing requirements of theAmericans with Disabilities Act (ADA). Theseproducts are commonly installed at the entranceto public buildings where concerns of pedestriantraffic and high heeled shoes coincide withneeds for ventilation and drainage.

S E R R AT E D S U R FA C EWhen the walking surface of bar gratings are subject to the accumulation of moisture or other slippery

substances, the optional serrated surface should be considered. Unlike rectangular mesh gratings where thebearing bars are typically constructed with the serrated surface, the standard method of manufacture for rivet-ed gratings is to serrate the crimped cross member. When the grating is assembled, these crimp bars areallowed to project slightly above the top surface of the bearing bars to provide a superior unidirectional skidresistant surface. Environments particularly prone to unsafe walking conditions can be further specified as100% serrated where both the bearing bars and the crimp bars are provided with serrations.

M AT E R I A L S A N D S P E C I F I C AT I O N SRiveted Gratings are produced in carbon steel, 6000 series

aluminum and 300 series stainless steels. To specify RivetedGrating, first specify the ttyyppee of grating from the table. In the instance of Standard Riveted Grating, The "RR""indicates the method of assembly shall be riveted construction, the ""1188"" indicates that the bearing bars shallbe spaced 18/16's (1-1/8) inches apart, and the ""77"" indicates that the rivets shall be spaced at 7" on center.Following selection of the ttyyppee of grating, consult the load tables to select the appropriate bearing bar size forthe loads and spans to be served. To complete the specification, indicate which of the three materials isdesired for the application, carbon steel, aluminum or stainless steel.

B A N D I N GBecause Heavy Duty gratings are commonly subjected to shock and impact

loads it is highly recommended that all open ends be banded. The welded band barhelps distribute impact loads and minimizes panel distortion when subjected torepetitious traffic patterns. Banding details can be found on page 3.

S E R R AT E D S U R FA C EOptional serrated bearing bars can be specified to enhance skid resistance. To

maximize skid resistance, specify 110000%% SSeerrrraatteedd grating. This Heavy Duty gratingis manufactured with serrated bearing bars and serrated rectangular cross bars.

B E A R I N G B A R S E L E C T I O NOnce the bar spacing is selected, the bearing bar size must be specified based

upon the anticipated load and the clear (unsupported) span to be served. The loadtables on pages 11-13 provide the maximum safe clear simple span for our mostpopular products based on the maximum traffic conditions defined. These tablesincorporate strict limitations where design deflection shall not exceed the lesser ofL/400 of the safe span indicated or 1/8 of one inch (.125).

C R O S S B A R S E L E C T I O NWhile bearing bar selection is critical for specifying a proper Heavy Duty grat-

ing for your application, the life-cycle of your installation will often be influencedby selection of the appropriate cross bar. The table below details alternative crossbar sizes available. The sizes listed for SSttaannddaarrdd LLooaaddss are the standard twistedsquare or round cross bars supplied by Grating Pacific for a particular bearing barsize. These sizes have been selected to maximize manufacturing efficiency andeconomy. It is suggested that these sizes be specified when the grating is subject tointermittent traffic and only occasional full capacity loading.

The cross bars listed for SSeevveerree LLooaaddiinngg are optional and will provide superiorrigidity and durability when gratings are subjected to intense, continuous or repeti-tious traffic. Ideal for trench covers, highways and inlet grates, these cross barsenhance lateral stiffness thereby extending the service life of the grating. Whenspecifying gratings with bearing bars centered at 1-3/8”, 1-7/8” or 2-3/8”, consider-ation of SSeevveerree LLooaaddiinngg cross bars is highly recommended.

NOTE: IN THE EVENT THAT A CROSS BAR SIZE IS NOT SPECIFIED, THE CROSS BAR SHALL BESELECTED AT THE DISCRETION OF THE MANUFACTURER.

elded Heavy Duty products are designed to meet the need for gratings subject toheavy rolling and static loads such as highways, plant floors, loading docks,

inlet covers and airports. Since these conditions can range from light-duty forklifts tosemi-trucks and trailers carrying maximum allowable highway loads, heavy duty grat-ings are manufactured in a wide variety of bar sizes and spacings.

Grating Pacific Heavy Duty products are designed in accordance with currentAASHTO specifications for H-10 through H-20 loads. Automobile and forklift loads aresimilarly evaluated with loads calculated and distributed in accordance with the crite-ria shown below. If your particular load conditions are not adequately addressed in theload criteria presented, please contact our engineering staff and we will be pleased toassist in the selection of a Heavy Duty grating to satisfy your specific needs.

HEAVY DUTY GRATING

BRIDGE DECKING

ridge Decking is manufactured by cold-press riveting truss shaped rreeccttiiccuulliinnee bbaarrss to rectangular bearing

bars. The resulting product is an exceptionally durable heavyduty grating with superior stiffness and lateral stability.Bridge Decking is often the preferred heavy duty grating forconcentrated or stress applications subject to impact andrepetitive loads. Common applications include bridge floors,highways, inlets, and airport trench drain covers.

The following table indicates fabricated dimensions for Steel Embed Frames presented above. Embed frames manufactured from stainless steel or aluminum are simi-larly available, but will vary dimensionally. Consult manufacturer for dimensions if critical.

T R E N C H G R AT I N G & I N L E T G R AT E SThe combination of Grating Pacific gratings and embed frames pro-

vides the specifier with a wide range of alternatives for drainage applica-tions. While any of the bar grating products and embed frames shown

on the previous pages can becombined for effective solu-tions, standard trench grat-ings and inlet sets are illus-trated on pages 15 and 16.Look there first for your mosteconomical solution todrainage requirements.

C U S T O M S E T SIf the standard sets

shown on pages 15 and 16do not adequately addressyour specific application ineither load capacity orappearance, please contactour engineering department.We will gladly assist in theselection of an appropriatealternative from our widerange of versatile products.

Grating Pacific EE--ZZ PPoouurr frames aredesigned to expedite forming and pro-vide superior concrete embedment.Assembled with continuous anchors onthe non-bearing sides, EE--ZZ PPoouurrframes install quickly and providesuperior drainage.

All frames are available in four sided, onepiece welded construction units and canaccommodate any clear opening. Simplyspecify the frame ttyyppee from the sectionsbelow, the desired clear opening, and thedesired grating or cover thickness.

mbed Frames cast into concrete floors and substructures serve a multitude of purposes that extend the effective life of your completed construction project. Frames form a permanent shield for concrete lead

edges and perimeters which are subject to cracking and chipping when left unprotected. During construction,these rigid 1/4" (minimum) thick steel frames expedite forming and provide a welded structure that assuresaccuracy in the concrete pour. Frames provide a uniform bearing surface for grates or covers, often eliminat-ing rroocckkiinngg or irregular elevations experienced with covers installed on poured concrete. In specifyingGrating Pacific Embed Frames, you are specifying durability, accuracy and economy. (Nail holes are optionaland may further expedite installation. If desired, size and location should be specified.)

TRENCH GRATING & INLET SETS

rench Grating Systems by Grating Pacific allow the specifier to combine any of the gratings illustrated above with anyof the embed frames profiled on page 14. Gratings are available in SSttaannddaarrdd series for pedestrian loads or HHeeaavvyy DDuuttyy

series for vehicular traffic. Unlike cast iron or molded trench products, this flexible system allows the user to specify theexact clear opening ("S" dimension) desired. BecauseGrating Pacific offers five distinct embed frame profiles,the user can select a frame to meet the exact edge condi-tion desired. Bolting the grates to the frames is optionaland must be specified. All gratings are provided with plainsurface (the optional serrated surface is also availablewhen specified) and open ends are trench banded to max-imize drain capacity. Unless otherwise noted, all trenchframes and grating are hot dip galvanized after fabricationin accordance with ASTM Specification A-123. Our mostpopular systems are listed in the table below, however,this listing in no way completely defines this comprehen-sive product line.

rating Pacific Trench Grating Systems and Inlet Sets combine our most popular gratings

and embed frames to provide economic, modularcomponents for construction projects. These prod-ucts are offered in our SSttaannddaarrdd series, designed toserve pedestrian loads, and our HHeeaavvyy DDuuttyy series,designed to service the most demanding vehiculartraffic. Each series is offered with multiple bar spac-ings (shown below) to address the specific needs ofyour application.

B O LT E D G R AT E SGrating Pacific Trench Systems and Inlet Sets

are manufactured as component products withthe grates easily removed for clearing debrisfrom the trenches or inlets. Often security con-cerns or traffic conditions dictate that the gratesmust be bolted to the framing. When thisoption is specified, weld lugs or counter-sunklands (below) are installed on the grates and thebolt is installed below the traffic surface of thegrating. For high security applications, boltedgrates with tamper-resistant fasteners may befurther specified.

INLET SETS

omplementing our trench grating systems, Grating Pacific Inlet Gratings and Frames provide the specifier with flexiblesolutions to inlet drain requirements. Equal to our trench grating products, Standard Duty pedestrian grates and

Heavy Duty vehicular grates are illustrated on page 15 of this catalog. Inlets may be specified to any clear openingby simply indicating the desired ""WW"" (width) and ""SS"" (span) dimensions illustrated on page 14. Similar toour trench grating systems, any of the five embed frame profiles may be specified to meet the exactneeds of your application. Bolting the grates to the frames is optional and must be specified.

While all gratings are manufactured with plain walking surface, the optional serrated surfacemay be specified. The ends of all inlet gratings are trench banded to enhance durability and allowfor maximum drainage. Unless otherwise specified, all inlet grates and frames are hot dip galvanizedin accordance with ASTM specification A-123.

FASTENERS & BANDING

PANEL WIDTHS & LAYOUT

FA S T E N E R SAll grating must be firmly fastened in place. Welding panels to the supporting struc-

ture provides a superior, permanent installation. Gratings subject to removal can be fas-tened with Weld Lugs which are shop welded between the bearing bars, or anchored withSaddle Clips. These fasteners, which are provided upon request, are punched with 5/16"holes to receive 1/4" bolts or screws (bolts or screws supplied by others). In areas wherewelding or drilling is not permitted, "G" Clips can provide the fastening solution. Theseclips install on the top surface of the grating and create a friction connection with theflange supporting the panel. The narrow spacing of close mesh gratings allows for coun-tersinking of the bearing bars and fastening with flat head screws.

PA N E L W I D T H SGrating panels are manufactured in nominal 24" and 36" standard widths. When considering alternative widths, consult the table below to select widths that will

maintain consistent oouutt--ttoo--oouutt spacing of the bearing bars. Widths specified which deviate from the table below can be fabricated utilizing side banding. In so doing,the outside bearing bar spacing on one side of the finished panel will deviate from the spacing throughout the rest of the panel.

PA N E L L AY O U TAs stated above, stock grating panels are manufactured in 24" and 36" nomi-

nal widths. Stock lengths (span) are 24'-0" for all sizes with most popular bearingbar sizes also available in 20'-0" lengths. These sizes allow for efficient layout andwaste minimization when they are fabricated to your exact specification.

Unlike many competing products, individual grating panels do not requiresupports on all four sides of each cut piece. Bar grating panels only require sup-port perpendicular to the bearing bar span. There is no need to place supportsparallel to the bearing bars where adjacent panels are installed in succession.

The following layouts illustrate proper layout and support of a simple bargrating platform.

GRIP STRUT® SAFETY GRATING

very year industrial accidents – falls, tripping over debris, slipping on wet or greasy surfaces – cost

millions of dollars in lost manhours and production. Byreducing accidents, insurance costs can frequently bedecreased. GRIP STRUT® Safety Grating helps reduce acci-dent rates by providing a safer walking-working surfacethan other grating products. Its serrated surface gives max-imum slip protection and performance under practicallyall conditions and in every direction.

The serrated surface is designed in an open diamondpattern. This allows drainage of fluids, mud, chips and otheraccident-causing debris.

In addition to safety,the resilient surface ofGRIP STRUT® SafetyGrating cushions theimpact of footfalls therebylessening worker fatigueand increasing efficiency.GRIP STRUT® SafetyGrating is your best safetybuy. These cost-cuttingand production-improv-ing advantages spell outwhy:

SAFER, SERRATED SURFACE – Grips soles securely – in alldirections – in practically every place. These non-slip GRIPSTRUT® Grating surfaces are ideal for inside or outsidelocations where mud, ice, snow, oil and detergents cancreate hazardous walking conditions. Openings are smallenough to catch most falling tools and other dangerousobjects.

MAINTENANCE-FREE OPEN DESIGN – Permits quick drainageof fluids, chips, grease and mud. Any ice accumulationshears easily under normal foot pressure. Open designallows convenient access for cleaning. It is easily cleanedwith brush, liquid or air spray to minimize overall mainte-nance.

HIGH LOAD CAPACITY, LONG LIFE – High strength-to-weightperformance is achieved through depth of section andstructural design. Bridged struts with integral side chan-nels form a plank that can support loads with minimumtransverse and longitudinal deflection. This sturdy con-struction provides the advantages of heavy load-carryingcapacity with minimal deflection; rugged durability withlonger-lasting performance.

FAST INSTALLATION – Light, easy-to-handle planks makeinstallation simple and quick. They can be handled byone man. Most sections are rapidly bolted, clamped orwelded into place, easily field-cut at virtually any angle, orfabricated to adapt to field conditions. Several attachmentdevices permit fastening to most existing surfaces allow-

ing for fast instal-lation or disas-sembly.

ECONOMICAL TOINSTALL, USE – Inaddition to lowmaterial cost andnominal erectioncost, GRIP STRUT®

Safety Gratingalso saves with itslong-lasting, rust-resisting materialsand finishes. Standardmill-galvanized finishresists corrosion to provide last-ing surfaces. High-strength alu-minum and Types 304 and 316L stain-less steel are available to provide maxi-mum corrosion resistance. Black unpaintedsteel is available for installations requiring hotdipped galvanized finish after fabrication. These light-weight but brawny panels permit substantial reduction instructural steel requirements. The open design is self-cleaning and virtually maintenance free.

VERSATILE IN APPLICATION – A variety of Standard widthsand channel heights combine with numerous Non-Standard shapes and sizes to meet almost any requirementof strength, size, durability, weight, finish, appearance andapplication. GRIP STRUT® Safety Grating combines safetyand durability with ease of fabrication andversatility. One piece construction mini-mizes the need for plant fabrication. Specialshapes and forming can be accomplished tosuit unusual requirements.

It’s simple and economical to apply fin-ish coatings because all surfaces are accessi-ble to brush or spray. GRIP STRUT® Gratingmay be hot dipped galvanized after fabrica-tion, anodized, plated, plastic-coated orotherwise finished to suit job requirements.

SERRATED GRIP STRUT GRATING – StandardSerrated Surface offers excellent slip resist-ance wherever maximum safety underfootis essential. Material meets anti-slip valuesset forth in Federal Specification RR-G-1602A.

NON-SERRATED GRIP STRUT GRATING – Forall-purpose use where a high degree of slipresistance is required plus a smoother tex-ture and design. Product is non-stock andsubject to extended lead time.

STANDARD GRIP STRUT GRATING PLANKS – Available inmaterials and sizes to meet most load/span requirements.May be used as is or banded, cut, welded, or punched tosuit requirements.

Tested by an independent laboratory for slip resistanceaccording to standards and methods established byFederal Specification RR-G-1602D, GRIP STRUT® SafetyGrating proved its superiority by exceeding all require-ments of this specification.

The standards were exacting – five shoe sole materialstested in three directions under five conditions: dry,greasy, muddy, soapy and icy. GRIP STRUT® Safety Grating

tested 10% to 180% more slip-resistant than similar mate-rials, depending on shoe materials and surface conditions.

Fewer accidents, with resultant lower insurance costsand reduced workman’s compensation losses, should bethe logical reason for specifying GRIP STRUT® SafetyGrating for walking-working surfaces and stair treads.

Values determined in accordance with standards forslip-resistance established by Federal Specification RR-G-

1602D. The values indicated are an average of valuesobtained for five sole materials (leather, boot rubber, shoerubber, Neolite and Hypalon) tested in three directions(longitudinally, transversely and diagonally) for the sur-face conditions noted. Values are in pounds of force nec-essary to move a 175 lb. load one inch across the surfaceof grating.

GRIP STRUT® SAFETY GRATING

GRIP STRUT® Safety Grating, determine load, clear span anddeflection requirements. Having this information, select from loadtable the appropriate plank to meet job requirements.

Example: Clear span of 4’-O”, concentrated load requirementof 300 Ib. at 0.25” max. deflection. Select from the tables follow-ing:

For eight-diamond 18-3/4” wide, 2-1/2” channel, 12-ga. steelwhich carries a load of 416 Ib. at a 0.18” deflection. This is one sizeto do the job. Other sizes will carry more load if necessary. Formore economical selection, choose the greatest width that will sup-port the load consistent with job requirements and choose deeperchannels rather than heavier steel gauges.

GRIP STRUT® Safety Grating will generally carry the same con-centrated load, tabulated in Ib. at mid-span, for a given span, mate-rial gauge and channel height, regardless of width. (See “How loadtables were prepared” described below.) The uniform load tables aretabulated in lb. sq. ft., which accounts for the difference in loadcapacity shown for various widths. Deflection is in inches.

HOW LOAD TABLES WERE PREPARED – The values shown in the fol-lowing tables are based on actual load tests conducted by an inde-pendent laboratory. The tables have been prepared in accordancewith the provisions of the AISI Specification for the Design ofCold-Formed Steel Structural Members, 1968 edition. To ensure thesafety of the tabulated loads, two aspects of GRIP STRUT® Gratingstrength must be considered.

The first consideration is transverse bending in the grating sur-

face, which is referred to as ssttrruutt fflleexxuurree. This occurs when thegrating is loaded with either a uniform load or a mid-width con-centrated load, and the ssttrruuttss (grating surface) deflect relative tothe side channels. To determine the allowable strut loads, samplesof each grating material and thickness were tested for each plankwidth. (See Fig. 1, below) The data resulting from these tests wasused to prepare ssttrruutt llooaaddiinngg tables, which give allowable loadsand deflections considering strut flexure only. These allowable strutloads, along with the results of additional tests performed on 8-and 10-Diamond grating, have been incorporated in the load tableson page 22.

The second aspect of GRIP STRUT Grating strength is channelflexure. This occurs when the channels at mid-span of the plankdeflect relative to support points. To verify the performance of theside channels, samples were loaded with concentrated and uniformloads at different spans (See Figs. 2 and 3). To approximate themost severe condition, there were no attachments between thechannels and the supports. In cases where spans are shorter, chan-nels deeper and planks wider, strut flexure becomes more critical.

3-, 4- AND 5-DIAMOND ALLOWABLE LOAD AND DEFLECTION TABLES –Since 2-through 5-Diamond planks are relatively narrow (less than1 ft. wide), it can be assumed that both side channels effectivelysupport the concentrated load and that the grating surface deflec-tion is negligible. Based upon these assumptions, values in the fol-lowing load tables for 2- through 5-Diamond have been deter-mined.

ALLOWABLE UNIFORM LOAD (U) – Values indicated in the rows adja-cent to “U” are the lowest of the (1) maximum allowable uniformloads considering channel flexure and (2) maximum grating sur-face flexure.

DEFLECTION CORRESPONDING TO “U” – Deflection values are indi-cated below the uniform loads and are the mid-span side channeldeflections for the planks carrying the allowable uniform loads(Fig. 3).

ALLOWABLE CONCENTRATED LOAD (C) – Values indicated in the rowslabeled “C” are the lowest of the (1) maximum allowable concen-trated load considering channel flexure (Fig. 2), with both channelseffective, and (2) the maximum allowable strut load (Cs) for a 1-ft.long sample (Fig. 1).

DEFLECTION CORRESPONDING TO “C” – Deflection values indicatedbelow “C” values in the tables are the mid-span, side channeldeflections produced when the allowable concentrated load isplaced at mid-span.

If grating surface deflection should be considered when select-ing a product to meet a particular specification, then the deflectionof the mid-width of the grating, relative to the side channels, canbe calculated using both the data in the Strut Loading Tables andthe Load Deflection Conversion formula below.

Load data based on yield strength of 33,000 psi for steel,23,000 psi for aluminum, 35,000 psi for Type 304 stainless steel,and 30,000 psi for Type 316L stainless steel.

In the elastic range, deflection is proportional to theapplied load for both uniform and concentrated loads. Thisrelationship can be used to determine the deflection thatany load which is less than the allowable load will produce.

8 & 10 DIAMOND LOAD TABLES

s width increases, grating strut flexure becomes much more important. Eight and 10-Diamond products are

wide enough to require a change in the assumptions used toprepare the 2-through 5-Diamond Product Selection/DesignTables. No longer will it be assumed that both side channelsare equally effective in supporting a concentrated load. Infact, to provide a high level of safety, one side channel willbe required to carry 100% of a concentrated load.

Also strut deflection for 8- and 10-Diamond productsmay be significant. The most critical case occurs when a con-centrated load is located at mid-span and mid-width. Todetermine how the struts perform under this loading, 3-ft.long samples of each material and thickness were tested. Forthese tests the side channels were continuously supportedand loads were applied using a 1-ft. long and 1-in. wide bar

placed parallel to the side channels at mid-width and at thelongitudinal center.

Results of these tests, included in the 8- and 10-DiamondProduct Design Tables, proved the performance of thesematerials when a concentrated load is applied at mid-spanand mid-width. If a concentrated load is to be applied at mid-width at the end of a plank, consult the ssttrruutt llooaaddiinngg table.

The following values have been tabulated for 8- and 10-Diamond grating:

ALLOWABLE UNIFORM LOAD (U) – Values are given in the rowslabeled “U” and are the lowest of the (1) maximum allowableuniform loads considering channel flexure, and (2) maximumgrating surface flexure.

DEFLECTION CORRESPONDING TO “U” – Deflection valuesappear in the rows labeled “D”, below the “U” values, and are

maximum deflections the allowable uniform loads wouldproduce. Maximum deflections will occur at mid-span andmid-width and will be the sum of side channel and gratingsurface deflections. (Fig. 3).

ALLOWABLE CONCENTRATED LOAD (C) – Values tabulated in therows labeled “C”, are the lowest of the (1) maximum allow-able concentrated load considering side channel flexure (withone side channel supporting the entire load-Fig. 2), and (2)the maximum allowable strut flexure (Fig. 1).

DEFLECTION CORRESPONDING TO “C” – Deflection values areindicated below the “C” values in the table and are deflec-tions the allowable concentrated loads will produce at mid-span and at mid-width. The deflection is the sum of sidechannel and grating surface deflections.

STANDARD GRIP STRUT®® FASTENERS

ll gratings must be firmly anchored in place. Welding planks to the supporting structure pro-

vides a superior, permanent installation. In areas wherewelding is not practical, or for installations where theplanks must be removable, the diamond anchors oranchor clamp assemblies illustrated below can providesuitable alternatives.

ROOFTOP WALKWAY SYSTEMS

24

oofs look durable – but in most cases they were never intended to be walked upon. As the volume

of rooftop equipment continues to expand, the wear andtear of mounting maintenance traffic can lead to leaks inroofing membranes and permanent roof replacement.

GRIP STRUT® Rooftop Walkways are a component sys-tem of GRIP STRUT® Safety Gratings and various supportbrackets, protective pads and hardware connectors. Thesecomponents can be incorporated at the design stage ofnew roofs, or assembled to retro-fit existing structures.

Unlike other products, this system is elevated to dis-courage shortcuts and emphatically define the path toservice rooftop equipment such as HVAC units andtelecommunications transmission equipment. Safety isprovided by the slip resistance of GRIP STRUT® SafetyGrating, renowned for safety in all types of weather.

In addition to safety, GRIP STRUT® Rooftop Walkwaysprovide unsurpassed life-cycle economy. Roofs last longer,with fewer leaks, and owners save on direct maintenanceand re-roofing expenses.

BOLT SEATS – PERF-O GRIP® Bolt Seats pro-vide a secure anchor of the grating to struc-tural supports. The standard bolt seat featuresoblong holes specifically designed to ensure avertical anchor (with a 3/8” bolt) even if thehole is off concentrically by as much as

1/4”. PERF-O GRIP® Double BoltSeats are available to maxi-

mize the attach-ment locationflexibility by pro-viding approxi-

mately 2” of longi-tudinal adjustment.

Available in mill-galvanized steel,aluminum and stainless steel.Hardware is not provided.

ERF-O GRIP® Grating’s unique surface of largedebossed holes and perforated buttons provides

maximum slip protection and performance under practi-cally all conditions and in every direction.

In addition to providing safety, the resilient surface ofPERF-O GRIP® Grating cushions the impact of foot-fallsthereby lessening worker fatigue and increasing efficiency.PERF-O GRIP® Grating is one of your best safety buys. Itcuts costs and helps improve plant productivity.

SAFE SURFACE – Grips soles securely - in all directions.Slip resistant PERF-O GRIP® Grating surfaces are ideal forinside or outside locations where mud, ice, snow, oil anddetergents can create hazardous walking conditions.

The circular openings (38% of surface area dependingon product size) are small enough to catch most fallingtools and other dangerous objects. But the self-cleaningopen design permits quick drainage of fluids, chips, greaseand mud while permitting ventilation and lighting flow.Ice accumulation shears easily under normal foot pressure.Open design allows convenient access for cleaning. PERF-O GRIP® is easily cleaned with brush, liquid or air spray ifdesired.

LONG LIFE – PERF-O GRIP® Grating’s high load capacityand long-life, high strength-to-weight performance isachieved through depth of section and structural design.Formed struts with integral side channels form a plankthat can support loads with minimum transverse and lon-gitudinal deflection. This sturdy construction provides theadvantages of heavy load-carrying capacity with minimal

deflection; rugged durability with longer-lasting perform-ance.

FAST INSTALLATION – Light, easy-to-handle planks makeinstallation simple and quick. They can be handled byone person. Most sections are rapidly bolted, clamped orwelded into place, easily field cut at virtually any angle, orfabricated to adapt to field conditions.

ECONOMICAL TO INSTALL AND USE – In addition to lowmaterial cost and nominal erection cost, PERF-O GRIP®

Grating also features long-lasting rust-resistant materialsand finishes. Standard mill-galvanized finish resists corro-sion to provide lasting surfaces. High-strength aluminum,Type 316-2D and Type 304-2D stainless steels are availableto provide maximum corrosion resistance. Black unpaint-ed steel is available for those installations requiring paint.Lightweight but brawny panels permit substantial reduc-tion in structural steel requirements.

VERSATILE IN APPLICATION – A variety of standard widthsand channel heights are available as well as numerousnon-standard shapes and sizes to meet almost any require-ments of strength, size, durability, weight, finish, appear-ance and application.

PERF-O GRIP® Grating combines safety and durabilitywith ease of fabrication and versatility. One-piece con-struction minimizes the need for field fabrication. Specialshapes and forming can be accomplished to suit unusualrequirements.

PERF-O® GRIP Grating may be hot dipped galvanizedafter fabrication, anodized, plated, plastic-coated or other-

wise finished to suit job requirements. Standard PERF-OGRIP® Plank is available in materials and sizes to meetmost load/span requirements. May be used as is, or band-ed, cut, welded or notched to suit requirements.

RATE-LOCK® Grating is an easy-to-install system of interlocking grating planks, treads and accessories

that provides safe, sturdy footing for mezzanine floors,platforms, walkways and other applications where non-slip performance is required. Hundreds of sole-grippingdimples insure a safe surface in all kinds of of weather andenvironments. The grating is available textured for saferworking surfaces, non-textured for wheeled traffic or rackdecking.

COST-SAVING DESIGN IMPROVES LOADING PERFORMANCE –The unique design of GRATE-LOCK Grating gives youmore design options – at less cost than other grating sys-tems. Increased load performance (see charts) has beenachieved through interlocking planks, stronger rungdesign and an expanded selection of leg heights andmaterial gauges. GRATE-LOCK Grating lets you specifylighter gauge steel for substantial material saving.

MORE SIZES, GAUGES – GRATE-LOCK Grating provides

the broadest line products of any manufacturer. Availablein three plank widths, four plank heights, three gaugesand lengths to 24’. Interlocking sections provide thestrength you need for extra-wide designs.

FULL LINE OF ACCESSORIES, TOO – Our line includes kick-plates, hold-down clamps, attachment hardware and stairtreads for complete job design.

FAST BOLT-TOGETHER ASSEMBLY – Save time in the fieldwith GRATE-LOCK bolt-together slotted assemblies.Kickplates and plank sections are prepunched. For addi-tional ease, planks can be straight, curved or angle cutwith hand tools.

SPECIFY GRATE-LOCK GRATING WITH CONFIDENCE – We haveconstructed our load tables using the most stringent inter-pretation of the AISI standards: Our safe allowable loadsguard against harmful local distortion as well as failure.Some manufacturers have prepared allowable load tablesguarding against failure only.

SAFETY GRATING STAIR TREADS

29

ll Safety Grating Products are excellent candidates for fabrication and installa-tion as stair treads. The versatile walking surfaces offered by Grip Strut, Perf-O

Grip, Grate-Lock and Traction Tread offer products suitable for nearly all applica-tions. Stair treads are manufactured with welded end carrier plates which are pre-punched with holes allowing the treads to be bolted to the stair stringers. In manycases, the side margin of standard safety grating channels provides a defined visiblenosing line. Where increased visibility and safety are desired, specify the productsshown with supplementary cast abrasive, Traction Tread, or formed checker platenosings.

The load data below takes eccentric loads into consideration. Although load val-ues include allowances for normal impact conditions and unusual pedestrian traffic,be sure to make provisions for special uses and loads involving unusual impact orvibratory forces. Load carrying capacity of stair treads increases as channel heightand gauge of material increase.

GRIP STRUTGrating is the only product that gives wall-to-wall teethper sq. ft. Serrated, diamond-shaped openings make GRIPSTRUT Grating 10 to 180% safer than conventional grat-ings – permits mud, oil, grease, and industrial waste to fallthrough when used over open floor material such as bargrating. Even ice shears free under normal foot pressure.Down-turned edges allow grating to lie flat and secureover existing flooring. Consult Grating Pacific for productspecifications.

Other important GRIP STRUT Grating advantagesinclude: easy field fabrication and fast, low-cost installa-tion. RM products available on special order in standardmaterial and sizes.

FIBERGLASS GRATING

33

ombining unmatched corrosion resistance with strength, long life and safety, fiberglass grating is

proven to deliver years of reliable service, even in themost demanding environments. Grating Pacific offers twotypes of quality fiberglass grating distinguised by theirmethod of construction. These gratings are classified asmolded products and pultruded products. Molded grating(illustrated on pages 35-38) is unmatched in its ability towithstand the effects of corrosion and is highly impactresistant. Pultruded grating (illustrated on pages 39-41)provides reliable corrosion resistance and higher loadbearing characteristics.

CHARACTERISTICS – Molded and pultruded fiberglassgratings are often superior to conventional metallic grat-ings when installed in highly corrosive environments.Fiberglass grating can be fabricated with simple handtools, is light in weight, and is easy to install. Forenhanced worker safety, fiberglass grating is slip-resistant,non-conductive, and is available with flame spread ratingsunsurpassed by any competitive product. In-line with thegrowth of ergonomics as a factor in facility planning, the

inher-entresiliency offiberglass grat-ing can alsoincrease worker pro-ductivity by greatly less-ening back and leg fatigue.

APPLICATIONS – The uniquefeatures inherent in fiberglass grat-ings make these products ideal candi-dates in the most demanding industrialapplications. Chemical processing, refining,offshore, pulp and paper, food and beverage,marine (including military vessels), water and waste-water treatment, electronics and plating are just some ofthe applications where the performance of fiberglass grat-ing has proven superior.

PULTRUDED GRATING

The resin systems used in fiberglass grating providesuperior resistance to the effects of corrosion and ultravio-let exposure. Uniquely formulated resin systems are alsoresponsible for the grating’s fire retardant characteristics.

Because various applications present different per-formance requirements, Grating Pacific offers a number ofstandard resin systems, each offering unique properties.For maximum versatility and selection, molded grating isstocked in five resin systems, the most extensive selectionin the industry. Pultruded grating is offered in two resinformulations, in order to best match the requirements ofthe specific application.

R E S I N S Y S T E M S

In keeping with its quality role, only FibergrateFiberglass Gratings are classified by UnderwritersLaboratory for meeting established standards for chemicalexposure, flame spread, load-bearing characteristics andslip-resistance. This certifica-tion by an independentthird party provides the usera strong sense of securityknowing that Fibergratemeets established perform-ance specifications. No othermanufacturer of fiberglassgrating can make that claim!

Pultruded fiberglass rein-forced plastic (FRP) embedmentcurb angle provides a secure anddurable seat for grating overconcrete trenches and pits.Manufactured from corrosionresistant, gray vinyl ester, fireretardant resin, curb angles arepultruded with a built-in contin-uous anchor that securely locks the angle into the con-crete pour.

FiberPlate sets the standard for high performancestructural panel. A rugged fiberglass structural plate with amolded-in, grit top surface, FiberPlate is designed for usein applications where durability andlong, maintenance-free life is critical.As a flooring, FiberPlate is usuallyinstalled over structural members, orover existing grating, to provide asolid walkway or to extend the life ofa high traffic area. FiberPlate can alsobe bolted directly to structural beamsand used as a wall panel that is resist-ant to corrosive splash. FiberPlate ismanufactured from the same widerange of resins and colors as our molded grating productsline. Available plate thickness is 1/8”, 1/4”. 3/8”, 1/2” and3/4” and plate sizes range from 3’-0” x 10’-0” to 4’-0” x12’-0”. Cut to size pieces are similarly available.

F I B E R P L AT ETo maintain corrosion resistance and structural

integrity, all exposed ends of fiberglass grating or compo-nents should be resin sealed after cutting. Grating Pacificoffers premium vinyl ester resin sealing kits for its fullrange of grating products.

THE LOAD AND DEFLECTION DATA PROVIDED IN THESE TABLES ARE INTENDED FOR USE AS A GUIDE ONLY, TO HELP DETERMINE GRATING SIZE FOR A GIVEN APPLICATION. THE USE OF DIFFERENT RESIN SYSTEMS AND TOPSURFACES CAN PRODUCE VARIATIONS, OF PLUS OR MINUS 20%, IN DEFLECTION. OPERATING CONDITIONS AND ENVIRONMENTS CONTRIBUTE TO THE PERFORMANCE OF THE GRATING. SINCE THESE CONDITIONS ARE NOTCONTROLLABLE, WE CANNOT GUARANTEE THE PERFORMANCE OF THE GRATING.

BECAUSE FRP PRODUCTS HAVE A LOW MODULUS OF ELASTICITY, BUT HAVE A HIGH TENSILE STRENGTH, LOADS ARE GENERALLY LIMITED TO THE ALLOWABLE DEFLECTION DETERMINED BY THE END USER. THE FOLLOWINGTABLES WERE PREPARED FOR USE WITH SUPPORTS ON TWO SIDES ONLY. THEY SHOW THE APPROXIMATE LOAD REQUIRED FOR A 1% DEFLECTION. TABLE I REPRESENTS WALKING CONDITIONS. TABLE II HAS TWO SETS OFNUMBERS, THE FIRST REPRESENTING DEFLECTION AT THE UNSUPPORTED END OF A PANEL, AND A SECOND FIGURE SHOWING FAILURE OF THE GRATING AT 10:1 SAFETY FACTOR (GRATING WILL FAIL AT TEN TIMES THELOAD SHOWN). TABLE III REPRESENTS AN EVENLY DISTRIBUTED, STATIONARY LOAD.

• HIGH STIFFNESS• MAINTENANCE FREE• NON CONDUCTIVE• CORROSION RESISTANT• SKID RESISTANT• LIGHTWEIGHT• UV RESISTANT

ultruded grating provides performance far exceeding that of alternative products with a comparable

installed cost. This advanced fiberglass grating is designedfor use in a wide range of applications that requirestrength and corrosion resistance. Manufactured with ahigh percentage of glass within the laminate, pultrudedgrating combines durability with the highest strength andstiffness available in fiberglass grating. Pultruded gratingcan be used with confidence in applications where widesupport spans are required.

Using both a mechanical and chemical lock, pultrud-ed grating is manufactured with a two-piece cross bar con-figuration which increase the panel’s support and sta-bility under load. The standard grit-top walkingsurface provides sure footing and a protectivesynthetic veil, covering the exterior surface ofthe load bearing bars allows the grating to reli-ably withstand constant exposure to ultravio-let rays.

Pultruded grating is available in two resin formulations for an accurate match of product characteristics with theapplication. Both resin systems provide corrosion resistance that is superior to that offered by metal grating.

ISOFR (YELLOW) – This isophthalic polyester resin formulation provides a low flame spread rating of 25 or less and isdesigned for applications where there is moderate exposure to corrosive elements.

VEFR (GRAY) – With a flame spread of 25 or less, this vinyl ester resin system provides dependable resistance to bothacidic and alkaline environments.

PULTRUDED GRATING RESIN SYSTEMS

Type ”M” 316 stainless steel hold down clips used tosecure panels to a support using two adjacent grating barsfor a secure fit.

Type “G” stainless steel hold clips designed to attachgrating to any structural member flange, 3/4” or smallerin thickness, with no drilling required.

Type “FB” 316 stainless steel flange blocks fit insideclose mesh products allowing for installation of capscrews from the top surface of the grating.

Type “RK” 316 stainless steel fasteners offer effectiveand more secure means for installing pultruded grating.

PULTRUDED GRATING LOAD TABLES

41

THE FOLLOWING LOAD TABLES WERE DEVELOPED IN STRICT CONFORMANCE WITH THE FIBERGLASS LOAD/DEFLECTION CRITERIA PRESENTED BELOW. U – UNIFORM IN LBS. PER SQ. FT., C – CONCENTRATED LINE LOAD INLBS. PER FT. OF WIDTH, ΔU – UNIFORM LOAD DEFLECTION IN INCHES, ΔC – CONCENTRATED LINE LOAD DEFLECTION IN INCHES.

MANUFACTURING CONTROL LIMITS – The load/deflection values given in this brochure aremedian values developed through a strict quality assurance program. The manufacturingcontrol limits on stiffness for all panels are plus or minus 7.5% of these median values.This represents the tightest control on performance variation in the industry, based pub-lished data.

ULTIMATE CAPACITY – Molded and pultruded grating product lines have been tested totheir ultimate capacities. Ultimate Capacity represents a complete and total failure of thegrating and is presented to illustrate the reserve strength of the grating at a given span.Ultimate capacities are not to be used for design; functionality of the grating is limited toMaximum Recommended Load.

BARS PER FOOT OF WIDTH – The preceeding molded grating load tables were developedusing 8 bars per foot of width for 1-1/2” square mesh grating and 12 bars per foot of widthfor rectangular mesh grating for uniform and concentrated loads. Some manufacturers use9 bars per foot of width and 13 bars per foot of width respectively. This can overstate grat-ing performance by as much as 12.5%. When comparing the presented products to thoseusing 9 or 13 bars, multiply the deflection reported in this catalog by 0.89 for square meshproducts, and 0.92 for rectangular mesh products.

WALKING LOADS – Walking loads, typically 50-65 PSF maximum or 250 lbs. concentrated pointload, are recommended for pedestrian traffic. Deflections for worker comfort are typically limitedto the lesser of 3/8” or Clear Span divided by 125; for a firmer feel, limit deflection to the lesser of1/4” or Clear Span divided by 200.

STATIC LOADS – The allowable loads in the tables are for Static Load Conditions at ambi-ent temperatures only. Allowable loads for impact or dynamic condi-tions should be a minimum of ONE-HALF the values shown.Long term loads will result in added deflection due to creep inthe material and will also require higher safety factors to insureacceptable performance. For applications at elevated tem-peratures, consult Grating Pacific. The designer is fur-ther referenced to ASCE Structural Plastics DesignManual.

FIBERGLASS GRATING CHEMICAL RESISTANCE GUIDE

ibertred Grating Stair Treads manufactured from quality Fibergrate molded grating exceed tough

OSHA standards for safety, strength, durability and corro-sion resistance. Fibertred is available in the same high per-formance resin formulations as Fibergrate molded gratingand also provides excellent safety characteristics – slipresistance, non-conductivity and a low flame spread.

Unique cutting channels, spaced at 6” intervals, pro-vide efficient utilization when custom fitting into stair-ways. These channels also ensure that all standardstairtreads widths are terminated with closed ends. A 1-1/2”

wide gritted strip is molded into the lead edge of the treadfor superior slip resistance. (Additional support is requiredfor treads exceeding 42” in width).

Cost efficient, durable Pultruded Stair Treads are slip-resistant and non-conductive. These stair treads offer thesame level of safety, strength and corrosion resistance asother pultruded fiberglass products. Designed for use inapplications where wider support spans are required,Pultruded Stair Treads are available in 1”, 1-1/2”, and 2”thicknesses.

EXPANDED METAL

REGULAR EXPANDED METALRegular Expanded Metal is an

open mesh, finished product thatis simultaneously die-cut andexpanded as it moves through pro-gressive dies on a press. In theexpanding process, the metal canbe expanded up to ten times its original size, lose up to 80% of its originalweight per square foot, and still retain form and rigidity. (Regular ExpandedMetal can also referred to as “Raised” or “Standard” Expanded Metal.)

FLATTENED EXPANDED METALFlattened Expanded Metal is Regular

Expanded Metal that has been passedthrough flattening rolls (cold rolled). Thisrolling process reduces the thickness ofthe sheet, stretches the pattern of thesheet, and provides a smooth flat finish.

All popular sizes are stocked in bothregular and flattened sheets.

FABRICATION

S H E A R I N GGrating Pacific has fabrication capacity and will

gladly shear perforated and expanded metals to specifi-cation. When shearing expanded metals, close atten-tion should be paid to bond and margin requirements.Pieces can be ““BBoonndd SShheeaarreedd”” or ““RRaannddoomm SShheeaarreedd””subject to manufacturing tolerances.

Bond shearing produces pieces with equal, closeddiamond configurations on all four sides. Randomshearing produces pieces with partial diamonds on up to all four sides. Random sheared pieces often havesharp exposed partial strands which should be protected by ““UU”” edging or finish framing.

When finish framing of expanded or perforated metals is desired, U-Edging is apopular option. Manufactured from 14, 16 or 18 gauge carbon steel in stock lengths,U-Edging is available 1” or 1-1/2” wide with openings that accommodate varioussheet thicknesses. Aluminum and stainless steel U-edging is available on special order.

MATERIAL: Indicate type of material desired (carbon steel, stainless steel, oraluminum).

STYLE NUMBER: Indicate style number (such as 3/4” - #9R) which will indicatethe desired diamond size and sheet thickness.

SURFACE: Confirm desired surface, regular or flattened sheet.

QUANTITY & SIZE: Indicate quantity desired and piece sizes including SWD andLWD. Provide material list for cut-to-size pieces and sketches for irregularshapes. For sheared to size orders, review shearing options illustrated above.

FINISHING: Specify any special finish requirements (galvanizing, paint or anodizing).

M AT E R I A L S / F I N I S H E SAll expanded metals are available in a variety of metals; carbon steel, stain-

less steel, and aluminum. Carbon steel expanded metal is lightly oiled andshould be cleaned prior to the application of finish coatings. Additionally, car-bon steel expanded metals can easily be painted or galvanized to enhance corro-sion resistance. (Certain popular carbon steel items are stocked galvanized.)

Aluminum products are stocked mill finish and can be anodized or epoxycoated. Stainless steel products are similarly stocked with a mill finish. Stainlesssteel can be electroplated to provide for a bright finish or abrasive blasted to pro-vide a uniform matte finish.

N O M E N C L AT U R EDIAMOND - The open area formed by strands and bonds. Normally the open area is diamond shaped.STRAND - The single metal strip that forms the perimeter of the diamond. The strand thickness is thethickness of the metal from which the expanded metal is produced. The strand width is the amount ofmaterial advanced before forming the next diamond.BOND - The point where adjacent strands intersect. The bond width is always twice the width of the strand.LWD - Long way of the diamond - indicates the distance from center-to-center of linear bonds in the long direction.SWD - Short way of the diamond - indicates the distance from center-to-center of linear bonds in the short direction.LWO - Long way of the opening - indicates the clear opening of the diamond in the long direction.SWO - Short way of the opening - indicates the clear opening of the diamond in the short direction.

T Y P E P C - P L A I N C R I M PSquare pattern wire cloth using warp and fill wires of equal size. Warp wirespass over and under fill wires in an alternating pattern at adjacent intersections.

Welded Wire Cloth is available in car-bon steel and select stainless steel alloys.

Manufactured in a wide variety of wirediameters, welded cloth is produced in a

square or rectangular mesh. Warp and fill wireslay flat and each intersection of Welded Wire

Mesh is electrically welded for maximum cross sec-tional strength. Welded Wire Mesh is available in

roll or flat panel form.

The strength and versatility created by the all-weldedconstruction make Welded Wire Cloth a preferred choice

for designers and fabricators. This rigid product can besheared, formed, fabricated and finished to the most demand-

ing specifications.

Popular for handrail infill panels, Welded Wire Cloth is available with attractive squareor rectangular mesh openings. Properly specified, Welded Wire Cloth conforms to current ADA

requirements. Grating Pacific will promptly provide stock panels for your own fabrication, or, ifdesired, we will gladly fabricate infill panels complete with framing and connection plates. Just ask!

WIRE CLOTH

52

WIRE CLOTH IS COMMONLY AVAILABLE IN THE FOLLOWING MATERIALS:

CARBON STEEL – plain low carbon steel typically ranging from C1006 toC1012 alloy, drawn from rod. Combines strength and weldability with econ-omy.

GALVANIZED BEFORE WOVEN – Carbon steel coated with a light layer of zinc dur-ing the manufacturing process. Adequate corrosion resistance is provided formost indoor applications, but not recommended for outdoor installations.

GALVANIZED AFTER WOVEN – Carbon steel coated with a heavy layer of zinc afterthe manufacture of the mesh. Excellent for long term corrosion protection.

HIGH CARBON STEEL – Abrasion resistant steel used for applications facing sig-nificant wear such as media filtering or sorting. Abrasion resistant steel canbe difficult to weld, consider mechanical fastening to supporting structure.

STAINLESS STEEL – Commonly manufactured in 300 series alloys. Type 304 ismost popular, but also available in types 309, 310, 316, 321 & 347. Series400 alloys are also available on special order.

ALUMINUM – Light weight and mildly resistant to corrosion, aluminum alloysare readily available. Alloy 1350 is most common and can be easily weldedand anodized. Also available are alloys 5056 and 6061.

NICKEL BASED ALLOYS – Inconel 600, Monel 400, Nichrome V and HastalloyC276 offer specific characteristics desirable in specialized environments.

SPECIALTY ALLOYS – Copper based alloys, bronze, brass and titanium are alsoavailable for all woven products. Contact our sales engineers for assistancein selecting the proper specialty alloy for your application.

CALENDARED WIRE CLOTH – wire cloth that has been passed through heavyrollers to reduce the thickness of the material or flatten the wire intersec-tions to produce a smooth surface.

CLEAR OPENING – the space between adjacent parallel wires.

CRIMPS – corrugations placed in the wire which allow the wires to bewoven together. The placement and style of the crimps determine thelocation of the intersections and permit tight locking of the wires.

FILL WIRES – wires running across the width or short way of the materialas woven. (Also referred to as shute or cross wires.)

GAUGE – a measure of wire diameter commonly used by manufacturers. Toavoid confusion between ferrous and non-ferrous gauge dimensions,always specify your desired wire diameter in decimal inches.

HARDWARE CLOTH – square mesh cloth, galvanized after assembly and avail-able in either woven or welded construction.

MESH – the number of openings in a lineal inch measured from the cen-ter of one wire to a point one inch distant.

OPEN AREA – the proportion of open space as a percentage of the totalmaterial area.

SELVAGE – a finished edge used to prevent fraying or unraveling of wovenwire cloth.

WARP WIRES – wires running parallel to the length or long way of thematerial as woven.

Open area, expressed as a percentage, is the ratio of clear area to screen area for a specific wire cloth. This ratio is useful for comparing how readily various materials or elements will flow through the cloth.

To calculate the open area of square mesh wire cloth, use the following formula:

EXAMPLE: To find the open area for square mesh wire cloth using 1/2" mesh , .120 wire:

(.500 – .120)2

(.500)2x 100 = 57.8% OPEN AREA

NOTE: WHEN ORDERING WIRE CLOTH, IT IS PREFERABLE TO STATE THE EXACT WIRE DIAMETER IN DECIMAL FRACTIONS OF AN INCH RATHER THAN WIRE GAUGE NUMBERS. CONFUSION BETWEEN STEEL WIRE GAUGE NUMBERS AND NON-FERROUS GAUGE NUMBERS CAN OFTEN LEAD TO IMPROPER OPENINGS BEING SPECIFIED.

ACO DRAIN

K L A S S I K D R A I N S – F E AT U R E S

CO KlassikDrain – K100S is a modular trenchdrain system whose components consist of a polymer

concrete drainage channel and versatile grating. Drainagechannels are commonly manufactured in one meter, 0.6%pre-sloping lengths. For enhanced design flexibility, selectchannels are also available in 1/2 meter lengths and “neu-tral”, non-sloping lengths. Grating alternatives range fromClass A pedestrian rated grates to Class E industrial ratedheavy duty grates.

POLYMER CONCRETE – ACO polymer concrete is a versatile, highly durable material with a smooth surfacefinish that is ideal for channel drainage. Polymer concretechannels are available with standard polyester or optionalvinyl ester resin binders, reinforced by mineral aggregatesand fillers. Compared to conventional concrete, polymers offer distinct advantages:

• LLow mmoisture aabsorption rrate• RResilient tto rrepeated ffreeze-thaw ccycles• SSmooth ssurface, llower ffriction ccoefficient, hhigher

hydraulic pperformance

• LLightweight• HHigher ccompressive sstrength

EASY TO DESIGN – ACO KlassikDrain K-100S systems areeasy to design. There are no complicated falls to calculate(built-in slope), and they are easily specified and detailed.The choice between different systems, loading capacitiesand grating selection make KlassikDrain systems preferredfor many applications.

EASY TO INSTALL – Layout of the system and installationof the channels is simple and efficient. Compared to the tra-ditional cast-in-place method, construction is quick andstraightforward, consuming far less field labor.

EFFICIENCY/PERFORMANCE – The smooth interiorradiused channel surface improves overall hydraulic per-formance. The removable grating permits easy access forcleaning and maintenance. The durability of the polymerconcrete improves and extends the service life of thedrainage installation.

K100S is a general purpose 4” wide drainage system suitable for interior or exterior applications. Available in thirty, one-meter long channels designed with a built-in 0.6% slope, the drain length can bemodified or extended beyond 30 meters by using “neutral” (non-sloping)or half meter sections. The K100S channel incorporates an integral cast-inmetal edge rail that reinforces the top edge of the channel including thegrating/cover bearing surface. In addition, to providing permanent and

distinct protectionthe edge rail is available in two metals; standard galvanized steelfor general applications oroptional stainlesssteel for corrosiveapplications. AllK100S channelsaccommodate locking grates inload classes Athrough E illus-trated on the following page.

4” internal width trench system -meter (39.37”) and half meter(19.69”) channel. ‘U’ shaped bottom improves flow hydraulics.

Interconnecting end profiles allow easy and effective joining of channels.Appropriate sealant can be used to create a sealed joint.

Polymer concrete - a durable, yet lightweight, material madefrom polyester resin binder reinforced by mineral aggregatesand fillers. It provides up to four times the compressivestrength of cement concrete.

Integrally cast-in galvanized steel edge rail provides additionalstrength and protects channel body from damage.(Stainless steel edge rail also available - KS100S).

Profiled side walls - strengthening pillars and frost keys provide channel body strength and mechanical keying to surrounding concrete.

Sloped (0.6%) channel units - meter long unitsprovide 98’-5” continuous slope. This equates to1/16" fall per linear foot. Neutral units can beused to extend run lengths.

Bottom drill-outs are included on all channel units to allow vertical evacuationof the system along the run. Schedule 40drill outs are sized for 4” and 6” pipes.

Note: For 6” pipes, an oval to round adapteris required (Part No. 95140).

Direction arrows on the sidesof the channel indicate flowdirection and ensure channelsare installed correctly.

lgrip is the new generation of slip-resistant flooring designed to provide safe

walking surfaces for the most demanding com-mercial and industrial installations. Engineered toprovide safe, sure footing in wet or dry condi-tions, Algrip has been tested for the most severeenvironments and has proven durable, functionaland superior.

M A N U FA C T U R EAlgrip Slip-Resistant Floor Plate is manufac-

tured through a patented CNC laser depositionprocess in which hundreds of rugged, customalloy slip-resistant laser deposits are delivered toeach square foot of a steel plate substrate in adefined matrix. This defined matrix provides slip-resistance in all directions allowing for the safeflow of traffic regardless of path.

D U R A B I L I T YThe durability of Algrip Slip-Resistant Floor

Plate originates with the steel substrate selectedfor each application. Available in steel sheets andplates as thin as 14 gauge, ASTM-A-569 steel,Algrip is also available in any thickness ASTM A-36 steel plate for structural applications. Whilethese durable steel substrates provide a solid foun-dation for the finished product, their strength isonly the beginning!

The true life-cycle of safety floor plates is tradi-tionally determined not by the substrate, butrather by the slip-resistant properties generated bythe traction surface. The traction providing laserdepositions on Algrip have been tested for hard-ness and adherence by independent testing labo-ratories and these results assure that this new gen-eration of flooring will provide unsurpassed serv-ice life.

Laboratory analysis has measured the hardnessof Algrip traction providing custom alloy laserdepositions at up to 60 on the Rockwell C Scale.Under repetitious pedestrian or vehicular traffic,these deposits will provide continuous, safe, effec-tive service. (Be reminded, that similar to all abra-sive surface steel safety floor plates, Algrip shouldnot be installed in areas subject to steel-wheeledvehicular traffic.)

The cross-sectional photograph below illus-trates the deep penetration of the symmetricallaser deposition into the steel substrate.Laboratory tested, the deposition penetrates thesteel substrate and is enclosed by a strengthenedheat affected zone. The resulting bond strength

combined with the proven depositionhardness provides unsurpassed durabilityregardless of wear or abrasion.

S A F E T YThe unique defined matrix application

of Algrip laser deposits provides unparal-leled slip-resistance in all directions. Thestandard .250 x .375 staggered matrixallows appropriate spacing for shoe solesand vehicular wheels to completely encir-cle and “grab” the deposits. With morethan 1500 deposits per square foot, Algripprovides superior safety and increasedpedestrian comfort. For applicationswhere ergonomics are a paramount con-cern, Algrip offers a safe, creative solution.

S L I P R E S I S TA N C E A N D C O FSlip-resistance is commonly tested in a

laboratory setting by measuring for staticcoefficient friction (COF) in accordancewith ASTM procedure C-1028. This testingprocedure assigns a value to the tractionsurface while that surface is tested underwet and dry conditions. Because the greatest con-cern for slip-resistance relates to worker/pedestri-an safety, this procedure can be further refined totest each condition using samples of commonshoe sole materials, leather, rubber and neolite(composition). The results of these tests areexpressed in numerical values with higher valuesindicating increased slip-resistance.

FEDERAL GUIDELINES FOR COF - The OccupationalSafety and Health Administration (OSHA) recom-mends that walking surfaces maintain a mini-mum COF of 0.50. The Americans WithDisabilities Act (ADA) recommends that levelwalking surfaces maintain a 0.60 COF and thatmaterials for inclined ramps maintain a morestringent 0.80 COF.

ALGRIP PROVEN SUPERIOR - The test results pre-sented in the table below demonstrate that Algripexceeds published Federal Guidelines in all condi-tions!

V E R S AT I L I T YAlgrip is manufactured with a standard .250 x

.375 staggered matrix. This pattern can be modi-fied to meet the distinct needs of specific applica-tions. Custom patterns have been developed toprovide defined visible nosings for OEM stairtread applications as well as specialty flooring

applications. Contact our engineering staff forconsultation on custom patterns and applica-tions.

E N V I R O N M E N TA LAll Algrip products are manufactured with

recycled materials and are themselves fully recy-clable. Unlike production of other slip-resistantfloor products, there is no accumulation ofsmoke, overspray or solid waste.

BONDEDABRASIVE

DIAMOND PLATE

A L G R I P. . . T H E T H I R D G E N E R AT I O NThe development of Algrip Slip-Resistant Floor Plate is the dawn of the

third generation of steel floor plate designed to assure safety in the work-place. The first generation of safety floor plate is commonly known as dia-mond or checker floor plate. This product is mill rolled with protruding lugsrunning in four directions. While this product was recognized as superiorwhen compared to smooth steel plate, in reality the product becomesextremely slippery when wet or worn.

The second generation of slip-resistant safety floor plate consisted of cov-ering the base plate with an abrasive surface either by mill rolling or bybonding a surface with a metalizing flame spray. These products have servedthe market adequately, however there are inherent drawbacks. The base platefor metalizing spray applications requires expensive surface preparationbefore the surface can be applied. Improper surface preparation often leadsto flaking or peeling of the slip-resistant surface significantly reducing thelife cycle of these products. Flame sprays are also applied at molten tempera-tures often leading to warpage of the plates upon cooling. Additionally, inmany cases the flexural properties of the abrasive surface are different fromthe base metal leading to laminations when subject to repetitive loads.Combined with these manufacturing difficulties, fabrication of the secondgeneration plates is similarly difficult. Forming the plate leads to unsightlycracking, peeling and tearing of the grit surface, and delamination of the sur-face can occur during galvanizing.

With Algrip 2000TM, the third generation of slip-resistant floor plates isintroduced to consumers. Algrip laser deposits are individual within thematrix and are tested with superior adhesion strength, thereby eliminatingflaking or peeling. Each deposit is applied to a highly concentrated area min-imizing heat buildup over the entire plate. This eliminates the warpage oftenassociated with second generation products. Finally, the hardness of Algrip

deposits combined with the high adhesionvalue allow the plate to be fabricated with-

out compromising the superior slip-resistant properties.ALGRIP 2000TM

E A S E O F FA B R I C AT I O NOne of the greatest advantages of Algrip is that it can be easily manufac-

tured into finished components using common metal working tools. Thesuperior adhesion of the Algrip slip-resistant surface allows the plate to befabricated by:

• WELDING • DRILLING • SHEARING • COUNTERSINKING • PRESS BRAKE FORMING • FLAME CUTTING • PUNCHING

F I N I S H O P T I O N S F O R A L L O R S O G R I L P R O D U C T SThere are five standard finishes available on all Orsogril products— from premiumto economical. If you need assistance selecting the finish that is right for your application, please contact your Grating Pacific representative.

Powder Coat Primer and Powder Coat Finish“Powder-Powder” finish is a superior architectural coating that provides a distinct finished appearance. Fabricated panels are first treated by abrasive blasting to remove mill scale and provide a clean, uniform surface. A corrosionresistant epoxy prime powder coat is then applied and cured by oven-baking.The panel is then coated with a TGIC polyester powder finish coat which provides ultraviolet protection and a smooth surface appearance. The finishcoating of 7-10 mils overall thickness is an excellent choice for both exteriorand interior applications where appearance of the surface must meet demand-ing architectural standards.

Zinc Plated and Powder Coat Finish “Zinc-Powder” finishes are well suited for interior applications and inland exterior applications. The primary plated finish provides corrosion resistance by coating the fabricated panel with a smooth, 1-2 mil protective layer of zincconforming to ASTM B-633. The panels are then etched to accept a finish application of TGIC polyester powder coating available in the full range of RAL color options.

Galvanized and Powder Coat Finish“Galvanized-Powder” is frequently specified as the superior solution for applications where corrosion resistance and the application of color arerequired. Finished panels are hot dip galvanized to provide a 3-5 mil coating ofzinc per ASTM A-123, and then etched to accept TGIC polyester powder coatingavailable in a variety of RAL colors. Recommended for outdoor applications,and considered particularly effective near coastal waters. It should be noted that the initial galvanized coating randomly exhibits rough texture that may beaccentuated by the application of the finish powder coating.

Galvanized Finish“Galvanized” panels provide excellent corrosion resistance for grilleworkexposed to atmospheric conditions. Commonly specified as an economical finish for outdoor applications, panels receive a 3-5 mil coating of zinc in accordance with ASTM A-123 after fabrication. It should be noted that hot dipgalvanizing is not considered an architectural coating. Galvanized products may randomly exhibit rough texture on the finished surface, dissimilar colorcharacteristics, and will oxidize when exposed to the elements.

Primer Coat Finish“Primer” finished panels are available with a wide variety of primer paint coatings. Primer finish is typically specified for applications where on-site finishcoatings will be applied to complement adjacent construction. Primer finishprovides limited corrosion resistance, and it is important to specify primers thatare compatible with the finish coat that will be applied.

Talia® 100 Fence Panel & Screening SystemConcealment and ventilation go hand-in-hand with Orsogril’s Talia 100 design. This elegant panel pro-vides 100% concealment by combining louvered bars permanently welded to round cross bars hiddenbehind the panel. A very economical and practical solution for screening and cladding applications.Perfect for concealing mechanical equipment and waste enclosures,while allowing 35% free air flow.

Talia® 80 Fence Panel & Screening SystemThe companion design from Orsogril for louvered panel requirements that allow aminimal amount of visual access, Talia 80provides a distinct look while providing aconcealment level of 80%, with 45% free airflow. The slightly larger open area allows for more free passage of air and light, whileat the same time concealing unsightly butnecessary amenities such as rooftop air conditioning equipment and ground levelelectrical transformers.
