Gray Iron - Best for Construction CastingsThe use of gray iron offers many advantages over other materials for construction castings.

Of all the common castable ferrous materials, gray irons exhibit the best corrosion and wear resistance as well as thedesirable quality of high compressive strength. These are valuable qualities for load bearing street hardware.

Strength:

Gray Iron produced by Neenah Foundry is laboratory tested from specimens to verify tensile strengths. Tensile strength is determined through the use of separately cast test bar specimens. Unless otherwise indicated within oracknowledged at the time of order, 35,000 p.s.i. minimum tensile strength iron is furnished. See "Test Bars Disclaimer" onpage 6 for further information.

When to Use Ductile IronDuctile Iron is an ideal material for construction castings when standard gray iron castings do not have the load bearingcapabilities for a particular application.

While having the advantages of Gray Iron, Ductile Iron has greater strength characteristics than structural carbon steelwithout steel’s inherent corrosion characteristics.

Ductile Iron is often used in areas subjected to loads greater than H20 loadings such as:• Industrial facilities with forklift traffic• Container Ports• Airports

Due to the excellent compressive strength of gray iron and the way these qualities relate to iron frames, mating ductile ironlids or grates with gray iron frames is often a cost-effective recommended approach.

There are many factors involved in choosing a grade of ductile iron. When there are unusual loading conditions or locations subjected to extreme heat or cold, please contact our Product Engineering Department for more information.

CASTINGS FOR DIFFERENT TRAFFIC CONDITIONS

To assist in selecting castings which meet a general load-bearing requirement, we have classified our castings into threeseparate categories. These are referenced as follows:

• EXTRA HEAVY DUTY: For airports and concentrated loads. These applications require special castings to accommodate wheel loads of 100 p.s.i. or greater. When selecting castings for heavy concentrated loads, advise loading conditions: total wheel load, tire or wheel contact area, and tire pressure. We will be happy to furnish you with information to assist you with your choice.

• HEAVY DUTY: Castings in this category exceed proof loads of 16,000 lbs. Many of the castings in this catalog are suitable for much heavier proof loads.

• LIGHT DUTY: These castings are recommended for sidewalks, terraces, and very light traffic. Specifiers are cautioned that it is possible for a site to be changed to a heavy duty requirement at some future date. If this happens, we strongly recommend that the installation be replaced with heavy duty castings. If in doubt, Neenah recommends specifying heavy duty castings.

LOAD BEARING CAPABILITIESResponsible consulting and public works engineers need to know how castings will perform in the field. For years empirical formulas have been erroneously used to determine loading capacities. Now Neenah offers full scale destructive testing as an accurate method of determining true load bearing capabilities.

FULL SCALE DESTRUCTIVE TESTINGProof load test is the recommended method of providing load performance of casting's service. You will find thistesting procedure explained in Federal Specification A-A 60005* and AASHTO M 306. The elements of the test are essentially these:1) A specified load is applied on a 9" x 9" area.2) The cover, grating or frame will be inspected for cracks or detrimental permanent deformation such as

buckling.3) Any crack or detrimental permanent deformation will cause the castings to be rejected.

Most tests are performed on our 200,000 lb. compression testing machine. Tests can take a casting beyond the A-A 60005* and AASHTO M 306 specification; even to destruction.

AVAILABLE PUBLISHED SPECIFICATIONSThere are several published specifications that are available to assist designers in specifying iron castings. It is the responsibility of the designer to determine if one or all of these specifications are appropriate for a given application. These specifications are referenced as follows:

For Gray iron • A-A 60005*-------------------------------Federal Specification – Frames, covers, gratings, steps, sump

and catch basin, manhole castings• ASTM-A-48------------------------------Standard Specification for Gray Iron Castings• AASHTO-M 105-------------------------Standard Specification for Gray iron Castings• AASHTO-M 306-------------------------Standard Specification for Drainage Structure Castings

For Ductile Iron• ASTM-A-536-----------------------------Standard Specification for Ductile Iron Castings• ASTM-A-897-----------------------------Standard Specification for Austempered Ductile Iron Castings

For Airport Castings• FAA AC: 150/5370-10, item D-751---Manholes, Catch Basins, Inlets and Inspection Holes• FAA AC: 150/5320-6, Appendix 3----Design of Structures for Heavy Aircraft

For Handicapped Compliance• Americans With Disabilities Act (ADA), Sections 4 Accessible Routes and Section 4.5.4 Gratings.

There may be applicable requirements and specifications other than those shown above that need to be consulted beforea designer specifies his requirements.*Replaced RR-F-621E as of May 26, 1998.

MODERN CASTINGS FOR TOMORROW’S WORLD

BREAKTHROUGHS IN CASTING CONCEPTS

Neenah makes continual effort to provide customers with the most modern and cost effective castings available.

PERFORMANCE CRITERIAIn times past, limited knowledge of the properties of gray iron caused specifiers to rely on weight as specifying criteriawhen calling for gray iron castings. In reality, the material properties of gray iron allow castings to be lighter in weight andthinner in section while still meeting or exceeding performance expectations. Proof load criteria, rather than casting weights, should be used in specifying construction castings. Various published specifications are available toassist specifiers with choices. See page 4 for a listing of published specifications.

CASTING WEIGHTSThe weights of Neenah Foundry castings are not shown in this catalog. Casting weights, section thicknesses and non-critical dimensions are periodically adjusted in a continued effort to bring our customers the best and most economical products available from our modern production facilities. Due to these occasional changes and adjustments, weights are not shown in this catalog in an effort to avoid confusion. Current weights are always available from Neenah.

Modern Platen LidsNeenah Engineers have known for some time that platen (plate shaped) lids are improved manhole covers which arepound per pound stronger than ribbed lids. Advantages of lighter weight, platen lids include:• Increased load capacity• Increased deflection resulting in increased energy absorption• Decreased weight• Easier to handle

Modern Lighter Weight Frames• Manhole frames have an inherently strong shape. In the past, metal sections had to be thicker

because foundry molding equipment was imprecise. To compensate, generous tolerances were required to ensure minimum section thickness.

• Today’s molding machines are capable of holding tight tolerances, allowing specifiers to reduce weights and section thicknesses. Technology now allows modern construction casting manufacturers to take advantage of the frame’s inherently strong shape.

• Modern frames are significantly reduced in weight and section thickness, without a reduction in relevant performance characteristics.

• Lighter frames are viable because gray iron is stronger in compression than in tension. The lighter frames are still so substantial that, under load testing, gray iron covers will fail well before failure of the frame.

PEDESTRIAN, BICYCLE AND HANDICAP CONSIDERATIONSNEENAH STRONGLY RECOMMENDS PROJECT DESIGNERS AND OTHER SPECIFIERS CAREFULLY CONSIDER PEDES-TRIAN, BICYCLE AND HANDICAP (ADA) ISSUES WHEN SPECIFYING THE USE OF CONSTRUCTION CASTINGS.DESIGNERS MUST RESPONSIBLY TAKE INTO CONSIDERATION VARIOUS CIRCUMSTANCES INVOLVING EACH SPE-CIFIC APPLICATION THAT MAY NOT OR COULD NOT HAVE BEEN ANTICIPATED BY THE MANUFACTURER.

NOTE: ALSO SEE “CHOOSING THE PROPER INLET GRATE” ON PAGE 108 AND “STORM WATER MANAGEMENTWITH NEENAH GRATES” ON PAGE 110.

AMERICANS WITH DISABILITIES ACT (ADA)PROJECT DESIGNERS AND OTHER SPECIFIERS MUST CAREFULLY CONSIDER AND IMPLEMENT THE REGULATIONSPUT FORTH IN THE AMERICANS WITH DISABILITIES ACT. PARTICULAR ATTENTION SHOULD BE PAID TO GRATINGTYPES AND THEIR LOCATION. NEENAH ADVISES A REVIEW OF THE REQUIREMENTS OF (ADA) WHEN DESIGNING APROJECT.

FASTENING FRAMES AND COVERS TOGETHER (FASTENING DEVICES)THIS NEENAH FOUNDRY CATALOG CONTAINS MANY ITEMS THAT HAVE COVERS FASTENED TO FRAMES USINGBOLTS OR OTHER FASTENING DEVICES. SPECIFIERS AND USERS MUST RECOGNIZE THAT BOLTS AND OTHER FAS-TENING DEVICES MAY HAVE A TENDENCY TO WORK LOOSE OVER A PERIOD OF TIME DUE TO TRAFFIC PATTERNS,VIBRATIONS, TEMPERATURE CYCLES, ETC. AND THAT ROUTINE INSPECTION AND MAINTENANCE SCHEDULESSHOULD BE IMPLEMENTED TO ASSURE THESE FASTENERS REMAIN TIGHT AND FUNCTIONAL. THEY MUST DETER-MINE THE NECESSITY AND FREQUENCY OF THESE INSPECTION AND MAINTENANCE INTERVALS FOR EACH INSTAL-LATION. PROCEDURES SHOULD BE ESTABLISHED TO ASSURE THAT MAINTENANCE CREWS CHECK FASTENINGDEVICES FOR PROPER FUNCTION AND TORQUE BOLTS TO YOUR ESTABLISHED REQUIREMENTS. CREWS MUSTREPAIR OR REPLACE FASTENING DEVICES, STRIPPED BOLTS AND THREADS PROMPTLY. CONSIDER EACH INSTAL-LATION INDIVIDUALLY TO BE SURE TRAFFIC OR USAGE PATTERNS WILL ALLOW THE USE OF FASTENING DEVICES.(SEE SECTION TITLED "GASKETED FRAMES AND COVERS" BELOW.

GASKETED FRAMES AND COVERSTHE NEENAH FOUNDRY CATALOG CONTAINS MANY ITEMS THAT HAVE NEOPRENE OR EPDM GASKETS PLACEDBETWEEN FRAME AND COVER. SPECIFIERS AND AGENCIES MUST RECOGNIZE THAT THESE GASKETS COMPRESSUNDER LOAD AND CAN RELEASE THIS COMPRESSED ENERGY IN THE FORM OF UPWARD MOTION WHENRELEASED RAPIDLY (SUCH AS NORMAL TRAFFIC LOADING). THIS ENERGY RELEASE MAY HAVE A TENDENCY TODISLODGE COVERS OR LOOSEN BOLTS IN BOLTED AND GASKETED UNITS. CONSIDER EACH INSTALLATION INDI-VIDUALLY AND CAREFULLY TO BE SURE TRAFFIC OR USAGE PATTERNS WILL ALLOW THE USE OF GASKETS. (SEESECTION "FASTENING FRAMES AND COVERS TOGETHER (FASTENING DEVICES)" ABOVE.

TEST BARS DISCLAIMERMOST GENERAL IRON CASTING SPECIFICATIONS REQUIRE PRODUCING FOUNDRIES TO MAINTAIN MINIMUM TEN-SILE STRENGTH PROPERTIES. THESE PROPERTIES ARE TO BE MEASURED ON TEST SPECIMENS MACHINED FROMSTANDARDIZED TEST COUPONS POURED FROM THE SAME IRON, BUT SEPARATELY FROM THE CASTINGS. TESTCOUPON DESIGN, DETAILS OF THE MACHINED TENSILE TEST BAR AND TEST CONDITIONS HAVE BEEN DEVELOPEDSUCH AS ASTM A 48 AND AASHTO M 306 TO PROVIDE MEANINGFUL EVALUATIONS OF SOUND, DEFECT-FREEMETAL UNDER STANDARDIZED CONDITIONS. THIS IS ONE OF THE FUNDAMENTAL PRINCIPLES UPON WHICHFOUNDRY OPERATION AND QUALITY PRACTICES ARE BASED.

SIGNIFICANTLY, THESE SPECIFICATIONS EXPLICITLY CAUTION THAT TENSILE PROPERTIES DETERMINED FROMSEPARATELY CAST COUPONS DEMONSTRATE THE POTENTIAL OF THE IRON USED TO MAKE THE CASTING. THEYARE NOT THE ACTUAL PROPERTIES POSSIBLE, LIKELY, OR TO BE EXPECTED IN THE CASTING. THE ACTUAL PROP-ERTIES DEVELOPED IN THE CASTING MAY DIFFER GREATLY FROM THOSE OF SEPARATELY CAST SPECIMENS ANDTHEY ARE, TO THE GREATEST DEGREE, DETERMINED BY FEATURES OF CASTING DESIGN. THIS IS MOSTLYBEYOND THE CONTROL OF THE PRODUCING FOUNDRY.

FOR THOSE PRIVATE CASTING SPECIFICATIONS WHICH REQUIRE TENSILE PROPERTIES TO BE DETERMINED FROMTEST BARS MACHINED FROM CASTINGS OR FROM ATTACHED COUPONS, THE DETAILS OF COMPLIANCE WITHTHESE SPECIFICATIONS AND THE COSTS THEREOF SHALL BE AS SPECIFICALLY AGREED BETWEEN THE PARTIES.ABSENT SUCH AN AGREEMENT, NEENAH FOUNDRY COMPANY DOES NOT WARRANT OR IMPLY THAT TENSILEPROPERTIES CALLED FOR IN A SEPARATELY CAST SPECIMEN WILL BE ACHIEVED AT ANY LOCATION IN THE CAST-ING(S).

WORKING WITH HEAVY CASTINGS CAN CAUSE INJURYCAST IRON PARTS, SUCH AS THOSE SOLD BY NEENAH FOUNDRY COMPANY, TEND TO BE HEAVY. IN AN EFFORTTO AVOID INJURY, NEENAH RECOMMENDS USERS ALWAYS USE LIFTING DEVICES WHEN HANDLING CASTINGS.PARTICULAR ATTENTION SHOULD BE PAID TO PROTECTING WORKER’S BACKS AND EXTREMITIES. IT IS THEUSER’S RESPONSIBILITY TO DETERMINE WHICH LIFTING DEVICE IS SUITABLE TO EACH SITUATION.

USERS SHOULD NEVER ALLOW ANY PART OF THEIR BODIES TO ENTER THE OPENING AREA OF AN OPEN HATCHCOVER UNLESS THE LID HAS BEEN SECURED IN A FASHION THAT WILL MAKE IT IMPOSSIBLE TO ACCIDENTALLYCLOSE. IT IS THE USER'S RESPONSIBILITY TO BE SURE THE CASTINGS ARE SECURE AND THE SITE IS SAFEBEFORE PROCEEDING.

NEENAH’s NO PAINT POLICY

Painting of Neenah construction castings has been discontinued for several reasons.

1. Asphaltic base paint contains volatile organic compounds or VOC’s. VOC’s are those air emissions coming from petroleum refineries, surface coating operations, and organic chemical manufacturing plants, to name a few. These compounds contribute to “air pollution” and are controlled under the authority of the United States Environmental Protection Agency and the Wisconsin Department of Natural Resources. In order to comply with the regulations of these agencies which limit the allowable amount of VOC’s emitted per gallon of paint, Neenah Foundry construction castings will not be painted.

2. Cast iron corrosion can best be described when compared to the corrosion of steel. The physical characteristics that differ between the two, include the greater concentrations of carbon and silicon in cast iron. These elements provide substantial corrosion resistance in gray iron.

Much of the carbon in gray iron occurs in the form of graphite flakes. This graphite is inert in most corrosive environments and provides a protective physical barrier against corrosion of the metal matrix. Technically speaking, it’s called graphitization. However, the graphite layer can mechanically be worn away exposing the iron to further oxidation.

Silicon in gray iron occurs in the metal matrix. When oxidation due to moisture initially occurs, a bright orange oxideresults. This loosely adhering oxide is water soluble and is easily washed or worn away. The presence of silicon in the iron eventually causes a much tighter adhering, insoluble, black oxide-iron silicate scale which inhibits further corrosion.

3. Painting of castings is cosmetic and, in fact, conceals defects which would be visible if the castings were unpainted.

4. The 1997 study, “A Guide To Standardized Highway Drainage Products,” states that painting, welding or plugging of cast iron castings is not allowed. This study was conducted by Task Force No. 13 under the sponsorship of the Joint Committee of the American Association of State Highway and Transportation officials, Associated General Contractors, and the American Road and Transportation Builders Association.

5. Attesting to its long life, cast iron water pipe is still in service today at Versailles, France supplying the famous foun-tains since its installation in 1664!

Neenah Foundry is continually upgrading its manufacturing facilities to provide the customer with a quality product. We also must protect the environment in which we live.

Non-Rocking Type Manhole Covers

NO NOISENO EXTRA COST

DOES AWAY WITH LOCKS

No Additional CostThe Non-Rocking Manhole Cover has long been a standard for noiseless function. Simple in design, it costs no more than an ordinarycover, yet one man can firmly seat a Non-Rocking Cover in a few seconds.

Simple, Quick AdjustmentAdjustment of the Non-Rocking Manhole Cover is made by placing the lid in the frame and then rotating it until the pointed lug on its edgeengages a corresponding slot in the frame. There are multiple slots, each of which changes the diameter of the opening. Moving the lidinto place is readily accomplished by placing a hook in the pickhole and drawing the lid around until it fits snugly. When properly posi-tioned, the Non-Rocking Cover will remain firmly seated in the frame without the use of asphalt or other filling. Removal of the lid may beaccomplished with equal ease.

R-1940-AAdjustable Manhole Frame, Solid Lid

Use for new construction, replacement pavement, or jobs where resurfacing is anticipated. Set con-sists of barrier support frame, adjusting frame and lid. For new construction, barrier frame is posi-tioned so that it will be slightly below finished road surface. Pave over top edge of barrier frame andgasket up to and flush with the top edge of the adjusting frame. When road is to be resurfaced,simply turn down the 4 adjusting screws and raise frame to desired grade. The lubricating greasecups around each bolt at the time of initial installation provide lubricant for adjustment. Then insertthe lock nuts for the bolt heads, replace the bolt well polyethylene caps, reinstall the 1/2” x 3/4”sponge neoprene gasket and the installation is ready for paving. All adjustments accomplished in amatter of minutes.

R-1955Floating Manhole

Heavy Duty

The “Floating Manhole” now provides an effective way of elim-inating the inflow of water at the junction of the cast iron frameand the concrete portion of the manhole. This is accomplishedby utilizing a two-piece frame with a molded rubber gasketconnecting the two halves and held in place with stainlesssteel bands. The upper half becomes an integral part of thepavement with the shear lugs transferring the wheel load tothe concrete pavement. The lower half of the frame becomespart of the manhole by imbedding threaded rods into the riserand bolting. This allows the manhole frame to “float” with thefrost action and maintain the integrity of the manhole.

When installed at the lowest position, approximately 3 inchesof rise can be handled effectively. The unit can be positionedto the correct grade at the time of installation by adjusting thethree bolts. Additional advantages include the ability to tilt theupper half coinciding with the longitudinal and transverseslopes of the streets to provide a smooth uninterrupted drivingsurface. If resurfacing at a future time, adjustment can beaccomplished by breaking the existing pavement around thetop half of the frame, and adjusting to the correct grade byusing the three bolts and the R-1979 adjusting rings.

R-1979 SeriesManhole Adjusting Rings

Heavy Duty

For raising manhole covers when pavement is resurfaced.

Adjusting rings or extension rings, as they are sometimes called, elimi-nate the necessity of raising or replacing existing manhole frame onresurfacing projects. The cover recess is the same depth and diameteras the existing manhole frame. Amount of raise coincides with thick-ness of resurfacing material, thereby bringing the manhole lid to newposition flush with refinished roadway surfaces.

Manhole adjusting rings can be placed rapidly and are a permanentinstallation. Use of adjusting rings may reduce raising costs to as littleas 20% of digging up the old manhole frame and resetting it to newgrade.

Adjusting Ring Installed

Cutaway View of Adjusting Ring Installation

CAUTION-WHEN ORDERING.

Be sure existing lid diameters are smaller than“AA” dimension as shown in table. “AA” dimen-sion in table is opening size in extension ring.Your lid should measure 1/4” to 3/8” less indiameter than this dimension.

The R-1982-J and the R-1982-W steps can be used as a fixed ladder.

R-1980-E R-1980-I For Circular Walls

R-1980-J Heavy ConstructionCast iron manhole steps are manufactured fromhigh tensile iron which has a minimum tensilestrength of 35,000 lb. per square inch. Actualload tests on castings have shown a generoussafety factor. Cast iron steps remain permanentlyin service because of their inherent corrosion resis-tant qualities. Cast iron steps are easily installed inconcrete, brick or block manholes. The tread isscored to meet safety requirements.

Steps should be installed in a vertical row on 16” centers.

CHOOSING THE PROPER INLET GRATE

Adopting an inlet grate design requires an analysis of the functions the grate should perform. A designer must review thedrainage requirements and then specify which functions will be necessary for satisfactory grate and all other performancerequirements of each application. For example, if the only consideration is for the grate to efficiently intercept large quantities of storm water from the gutter - then a grate with the proper geometry and flow through area is the one tochoose. Although capacity is an important function, there are other considerations that must be evaluated to satisfy therequirements of a functional, correctly located, safe grate. Some considerations are listed below. Designers must note that there may be other considerations in addition to those listed below that should be evaluated prior to making a choice.

NOTE: ALSO SEE “CAUTIONS” ON PAGE 6 AND “STORM WATER MANAGEMENT WITH NEENAH GRATES” ONPAGE 110.

CONSIDERATIONS FOR HANDICAPPED PERSONS, BICYCLES AND PEDESTRIANSDesign and placement of the grate must be suitable for use in areas where it is possible for handicapped persons, bicycles,and pedestrians to be present.

THE ADOPTION OF THE AMERICANS WITH DISABILITIES ACT (ADA), THE PROMINENCE OF NARROW TIRED BICYCLES AND CONCERN FOR PEDESTRIAN SAFETY DICTATES THAT DESIGNERS CAREFULLY CONSIDER THE SAFETY OF THE TYPE OF GRATINGS SELECTED FOR VARIOUS APPLICATIONS. IF THE INSTALLATION IS CHANGEDIN CONCEPT, SCOPE OR USAGE PATTERN AT SOME FUTURE DATE, DESIGNERS MUST AT THAT TIME RECONSIDERTHE TYPES OF GRATINGS USED AND DETERMINE IF THEY STILL MEET THEIR SAFETY REQUIREMENTS. IF NOT,DESIGNERS MUST REPLACE THESE EXISTING GRATES WITH MORE APPROPRIATE STYLES.

GRATES FOR BICYCLES The designer must determine the appropriate grate design and inlet location for safe use bybicycle traffic, having in mind the specific details of location and foreseeable use. The following are some important considerations:1. The style of grate employed should allow bicycle travel from all accessible directions. Grates located in open

areas, or adjacent to driveways, or in other locations where they are not adjacent to barrier curbs, require special attention in this regard.

2. In general, we suggest consideration of our Type L vane style grates. We think certain grates shown in our catalog are generally not suitable for use where bicycle traffic is a consideration, and those grates are so designated in this catalog. The absence of such a designation, however, does not mean that a grate would necessarily be safe in any specific location, and the designer is responsible for making the appropriate grate selection.

3. If slotted grates or vane-type grates other than our Type L are considered, they should have sufficiently narrow openings, and/or should have appropriately spaced transverse (cross) bars, to ensure that any foreseeable width and diameter of bicycle tire cannot drop down into openings to an unsafe extent.

4. Gutter slopes should not be substantially swaled into the curb so as to create a disturbance in the roadway which might affect the ability of bicycles or other traffic to traverse them.

GRATES FOR PEDESTRIANS AND HANDICAPPED Various regulations or customs may dictate the use of specific typesof grates: such as gratings with longitudinal slot openings no greater than 1/4” or 1/2”. Designers must carefully evaluatethe location and placement of grates against applicable specifications to be sure they are using grates that will satisfy thespecification's requirement and provide a pathway (accessible route) for pedestrians and handicapped persons. TheAmericans With Disabilities Act (ADA) provides grating specification guidelines that can be used in creating accessibleroutes for handicapped individuals.

HYDRAULIC EFFICIENCYThe ability of a grate to intercept storm water or its hydraulic efficiency is an important function. The main considerations indesign are the geometry and the flow through area of the openings for each individual grate. NEENAH has recognized thedesigner's need for hydraulic information on individual grates. We studied individual grate performance by establishing ourown hydraulic testing program and are now capable of supplying grate capacity information on most of the grates shown inthis catalog. Please call us for specific charts and information or to request your copy of Neenah's Inlet Grate CapacitiesManual.

109

SCREENING OUT HARMFUL DEBRISAn inlet grate must act as a strainer and prevent harmful debris from entering sewer lines. Objects such as branches, largesheets of semi rigid material, sticks, chunks of wood, etc. which are easily passed by large curb openings (open throat) areconveniently prevented from entering the catch basin by a well chosen grate.

If large debris gets into the catch basin, it can often float or wash into the lines, clogging them at inaccessible locationsand making the drainage system ineffective.

Should clogging of the grate occur at the upstream end, grates of longer lengths usually provide the extra flow throughcapacity necessary to accommodate the gutter flow as well as some of the side flow.

ABILITY TO PASS UNOBJECTIONABLE DEBRIS Organic material, such as grass clippings, leaves, small stones, scraps of paper and even small twigs should be passedinto the catch basin. Because of their size and configuration they are not a hazard for the sewer lines.

Grates designed with closely spaced bars for strength and safety become easily clogged from very small but always present debris. The problem is magnified even more as this debris is packed into the openings by passing traffic creating a hard, semi solid surface. The velocity of the gutter flow is insufficient to dislodge the packed debris and so the gratebecomes ineffective.

The answer then is to provide grate openings wide enough, of suitable length or of special design to pass this debris andstill meet the other requirements. Neenah has many sizes and styles that can be implemented into your designs.

STRENGTH Inlet grates placed in roadways must be designed to withstand heavy traffic loads. A common designation for standardhighway loads is described as H20-44 loading for single axle trucks and HS20-44 for tandem axle trucks (tractor semi-trailer units). The maximum axle loading in both cases is 32,000 lbs. Or 16,000 lb. for each set of dual wheels. There may be cases where more extreme design loads are necessary such as airports, commercial applications, industrialsites or installations where extra heavy loads and/or extremely hard tires are present. (See page 4 for a list of publishedspecifications available to assist you in your design.)

PERMANENCY A gutter inlet grate should be designed to match or exceed the expected life of the installation. The inherent rust resisting properties of unpainted cast iron and its time-tested performance insures long life. The strength ofcast iron grates resists earth and pavement pressures-qualities one should question in other non-cast iron materials.

110

An important consideration in any storm water management plan isthe proper selection and use of drainage grates. The NEENAH lineof inlet, area and drainage grates offers hundreds and hundreds ofchoices. Different shapes, sizes and geometry provide varyingcapacities which can match your inlet and outlet control require-ments.

When runoff conditions overtax sewer lines or treatment capacity,engineers frequently detain excess storm water by temporarilyimpounding storm water in suitable depressed open space areas,parking lots or other available basin type structures. With NEENAHcapacity rated grates, ponded water can be slowly released at acontrolled rate as sewer lines and treatment facilities are able toaccept new discharges. (see pages 326 to 330 for the free openareas of many Neenah grates.)

We have listed some of our usage specific drainage grate productsbelow for your consideration.

STORM WATER MANAGEMENT WITH NEENAH GRATES

TRENCH FRAME AND GRATE

For draining large impervious areas, many designers specify

NEENAH trench drains. Sizes range from 6” to 48” widths.

Drains can be installed in any length with direction changes to

suit the area and drainage conditions. Other types are sup-

plied with cast iron box frames in 5” and 10” widths. (For

details see pages 282 to 287.

MEDIAN DRAIN AND FREEWAY DRAINAGE GRATES

Stormwater management on freeways is important so that

roads are safe for motorists during wet weather. NEENAH

offers a variety of choices for inlet boxes, median inlets or

ditch checks. See pages 236, 237, 257 to 263.

HIGH CAPACITY VANE STYLE GRATES TYPE “L” GRATE

Neenah's high capacity vane style grates offer designers the best

combination of hydraulic efficiency and safety for triangular gutter

slope applications. For details, see page 112.

TYPE “L” VANE STYLE GRATES

CAPACITYAn important function of an inlet grate is capacity - the ability tointercept the storm water from the gutter. Hydraulic tests provethe Type “L” Vane Style Grates will accept more water than anyof the conventional grate styles under virtually all flow condi-tions. Even with extremely high volume and velocity conditions inthe gutter, there will be very little if any water that the grate willnot capture, providing the water passes over it. The efficiency ofthese grates can be as much as 20% greater than conventionaldesigns. For this reason, an ever increasing number of States,Counties, and Municipalities have adopted the Type “L” VaneStyle Grate as a standard.

GRATE REPLACEMENTType “L” Vane Style Grates are being used in grate replacementprograms in many cities throughout the country, not onlybecause of their storm water capacity features but also becausethey are more likely to be safe for bicycles than many otherstyles of grates. A replacement high capacity, Type “L” grate canbe dimensioned to fit most catch basin inlets. Our ProductEngineering and Sales Departments are available to assist you indeveloping your grate replacement program.

BICYCLE GRATESIn addition to its increased capacity, the Type “L” Vane Grate isalso being specified when bicycle traffic is a consideration.These grates, when installed either in a gutter line or in an openarea can provide desirable features for use when bicycles arelikely to be present. (See Page 6 (Cautions Page) and page 108for additional information regarding bicycle safety.)

DEBRIS A properly functioning inlet grate such as the Type “L” VaneStyle Grate must screen out the larger, harmful debris and pre-vent it from entering and clogging the sewer pipe. Small debris,however, which can be easily handled by the underground por-tions of the storm sewer, are allowed to pass through the grateopenings to prevent blockage on the surface of the grate.

Airport construction castings should be selected to sustainthe loading requirements of a Boeing 727-200 and LockheedL1011-500 aircraft. Although not the heaviest aircraft, theload is concentrated on their gear configurations makingthem effectively as heavy a loading to which constructioncastings will be subjected. Individual wheel loads of variouscommercial aircraft are shown in the table at right.

The FAA indicates for heavier dual gear aircraft, the assumedspacing of 34" between centerline of the tires is reasonable.Based on this assumption, construction castings with clearopenings greater than 34" can be subjected to loadingsgreater than that of one wheel. However, due to the distribu-tion of this loading on the casting, the effective loading maynot necessarily be as critical as a single concentrated wheelload in the center of the casting.

Notes to project designer:

• All items shown in Neenah's Aiport Series are capable ofwithstanding minimum 100,000-pound loads as called forin FAA Advisory Circular AC 150/5320-6D Appendix 3 Item 2.d. (1).

• All items shown in Neenah's Airport Series will be furnished with covers or grates fastened to frames as called for in FAA Advisory Circular AC 150/5370-10A.

• All items shown in Neenah's Airport Series will be furnished unpainted per FAA Advisory Circular AC 150/5370-10A.

• Castings furnished in Austempered ductile iron per ASTM A 897 are furnished per FAA Advisory Circular AC 150/5370-10A.

• Slotted vane drain shown on page 205 is furnished per FAA Advisory Circular AC 150/5370-10A.

Military installations may have heavier loadings than commer-cial airports, in which case, contact us regarding the tire pres-sures, contact area and wheel spacing.

The Boeing 727-200 (illustrated at right) is consideredbecause of the possibility that the spacing of wheels is suchthat 2 wheels may be concentrated on one casting.

The Neenah R-3475-E thru Infinite Series of airport drainage inlet frames and Ductile Iron Grates is our most popular air-port inlet grate offering. Designers tell us they like the comfort of knowing that ductile iron, produced by Neenah Foundry,is the best choice of materials for those critical inlet installations.

Advantages of Ductile Iron R-3475 Grates by Neenah

• User confidence that ductile iron by Neenah is the best choice of materials.

• Super strong ductile iron grates need only be supported on the two short sides, providing for an unobstructed clear opening.

• Less installation expense because ductile iron’s strength negates the need for galvanized steel “I” beam crossmember supports between grates.

Mooring Eye is placed on subgrade and filled with sand to exclude concreteduring the pouring and finishing operation. Sand is easily washed out whenpaving is completed. Opening at bottom of Eye is socket for wood or metalstake to bring Eye to grade. Square socket design prevents displacement whileconcrete is being poured and, if required, the hole provides drainage to the sub-grade after Eye is in place. Alternative method of setting is to push the Eye inposition in the wet concrete. Both methods are approved.

When used with bituminous slab, the Eyes should be set in concrete basebefore paving. Design permits in-flowing of concrete, and wide base insuresproper anchorage.

Ribs on R-3490 and R-3490-A have 1/2 inch holes for reinforcing rods, if needed.R-3490-B has 1 1/8 inch cored holes in ribs.

For rope, clip, and hook type anchor. Bars tested towithstand ultimate load of 9,000 lbs. in bending.

Airport Slotted Vane Drain

NEENAH’s Cast Iron Slotted Vane Drain offers ease of installation along with the superiorvaned configuration to capture previously unexpected quantities of water when placedperpendicular to the flow. Installation is accomplished by sawing a slot in the top of con-ventional PVC pipe, placing the pipe on grade, installing the Cast Iron Slotted Vane Drainin place and pouring the concrete. When used in conjunction with a vane grate inlet, virtu-ally all of the water in the street, which would normally bypass the catch basin, can be cap-tured. This permits the spacing between inlets to be increased. An additional benefit is theadded safety factor obtained should the catch basin be plugged or covered with snow. Theunit may also be installed wherever sheet flow capture is required.

Feel free to contact our field personnel or our Product Engineering Department at Neenahfor further detailed information.

Order as R-3599-A

Bolts not furnished.

Slotted vane drains shown are allowed per FAA Advisory Circular AC 150/5370-10AChange 11.

R-3599-ASlotted Vane Drain, Sheetflow

NEENAH’s Cast Iron Slotted Vane Drain offers ease of installation along with the superior vaned configuration to capture previously unexpected quan-tities of water when placed perpendicular to the flow. Installation is accomplished by sawing a slot in the top of conventional PVC pipe, placing the pipeon grade, installing the Cast Iron Slotted Vane Drain in place and pouring the concrete. When used in conjunction with a vane grate inlet, virtually all ofthe water in the street, which would normally bypass the catch basin, can be captured. This permits the spacing between inlets to be increased. Anadditional benefit is the added safety factor obtained should the catch basin be plugged or covered with snow. The unit may also be installed atentrances and exits of parking areas to capture sheet flow before it enters a commercial street.

Bolts not furnished.

Feel free to contact our field personnel or our Product Engineering Department at Neenah for further detailed information.

On longitudinal slopes of 0% to 6%, this unit captures approximately 0.5 cubic feet per second, per lineal foot.

R-3700 to R-3708 Series

Cast iron catch basin traps are used extensively onsewer catch basins or manholes to prevent clog-ging on sanitary systems. They provide awaterseal against escaping gases. Traps with droptype catch basins provide effective means ofkeeping pipe lines entirely clean. The drop portionof inlet retains all solid material and the trap pre-vents all floating debris from entering outlet pipe.All catch basin traps shown are of approveddesign.

SQUARE AND RECTANGULAR DRAINAGE GRATES

Heavy Duty (unless noted otherwise)

The gratings in this series are rated heavy duty when supported on all four sides.

Other special sizes quoted on request in the event none of the standards shown in thisseries meet your requirements. In ordering replacement grates to be used on existingcatch basins, be sure to specify the exact size of opening in which the grate will beused.

Many of the grates in this series can be adapted to trench frames with support on twosides as shown on pages 282 and 283. Most are qualified as heavy duty when the shortdimension spans the trench.

Advise loading requirements so we can assist you with your choice.

Specify:

1. Catalog number.

2. R-4899 angle frame when required. (See page 270)

3. Perma-Grip surface if required. (See page 10)

The above schematic drawing identifies basic dimensions only and does not apply to all grate designs. Bar and rib depths, plate thicknesses, and seatingwidths, may vary on different sizes and styles. If your project has design restrictions, ask for approval drawings.

Both then are held in place by using a 9 gauge wire to force the frame intothe proper position (Figure 3a & 3b). Frames should butt together snugly,leaving as little gap as possible to eliminate any “creep” if the installationsare long. Place a #3 bent rebar through the holes in the anchor lugs toprovide additional anchorage in the concrete. Prior to pouring the con-crete, verify the annular space allowance (space between the edge of thegrate and frame) so grates will fit properly in the space allowed. Thisshould be 3/16 inch (Figure 6).

Suggested Forming Procedures For InstallingNeenah Drainage Structures

Heavy Duty

For those who are not experienced in the installation of Neenahdrainage structures (R-4990 and R-4999 series), the following proce-dures are one way of achieving desirable results.

Materials

Under normal situations it would be customary to use a good grade ofweather resistant 3/4 inch plywood for forming walls. Constructiongrade 2 x 4’s are suitable for studs, plates, bracing and spreaders. Theamount and position of the bracing, studs and spreaders to assure asafe working environment is a function of site conditions along withthe depth and width of the trench. A typical installation is shown inFigure 1. Details shown and suggestions are based on using theNeenah Foundry Type X frame.

Forming Procedures

Once the floor slab of the trench has been poured and cured accord-ing to the plans and/or specifications, begin the forming procedure.The width of the forming (see Figure 1), measured from the outsideedges of the forms, corresponds to the “C” dimension in the catalogand on Figure 6. During the entire forming procedure, continually veri-fy that the forms are PLUMB, STRAIGHT, SOLID and LEVEL.

The height of the form corresponds to the final grade elevation wheninstalling the non-bolted frame and grates. Extend the spreadersbeyond the edge of the forms as shown in Figure 2a to provide a stopfor the frame and seat form. Once the elevation has been verified andthe forms are level, begin attaching the frames to the formwork.

To attach the C.I. frame to the forming, the use of a “seat form” is recom-mended to assure that the frame is at the proper elevation and level. Theseat form has the same dimensions as the frame, with the height corre-sponding to the frame height ( the “B” dimension in the catalog), and thewidth the same as the seat width of the frame. The seat width should befield measured to assure a proper fit. All Neenah frames have a slightradius at the corner of the seat and vertical face so the seat form shouldbe beveled to accommodate this radius and assure that solid contact ismade along the entire length of the C.I. frame.

Several methods may be used to attach the C.I. frames - two are shownhere. One involves attaching the seat to the frame using the holes in theface of the frame to nail it in place (Figure 2a) and the other requires nail-ing the seat form to the framework (Figure 2b).

287

Forming Procedures Continued

BOLTED UNITS

When bolted frames and grates are furnished, they are shippedassembled (see Figure 4a) and therefore require different formingprocedures. AT NO TIME SHOULD THE UNITS BE DISASSEMBLEDDURING INSTALLATION! DO CHECK THAT THE 3/16” GAP HAS NOTCHANGED IN TRANSPORT.

The height of the side of the form is such that the top of the form isthe final grade minus the seat depth of the C.I. frame (this is actuallythe same as the “B” dimension referred to in the R-4990 seriesshown on page 285. Figure 4b illustrates the positioning of the cast-ing on the forms.

Once the elevation has been verified and the forms are level and braced,begin installing the frame and grate units on the forms. Be sure to keep thesections tight up against one another to eliminate creep due to spacingvoids. When the sections are in the proper position, wire them to the bracingas shown in Figure 5. Place a #3 bent rebar through the holes in the anchorlugs to provide additional anchorage in the concrete.

Once the concrete has been poured and cured, strip the forms and removeany exposed wire which was used to secure the grate or frames to theforms. The completed installation should resemble the illustration shown inFigure 6.

General CommentsNOTE: All frame sections are furnished in standard manufacturedlengths. It is the responsibility of the installer to cut frame pieces to theproper length and to miter corners where applicable. In cases wheretrench direction must change, special drawings will be furnished by ourEngineering Services Department. These prints will show special gratelengths and cuts, as well as other essential information. Forming proce-dures, however, are basically the same.
