LYSAGHT® TOPSPAN 61 / 120Light steel sections.

TOPSPAN 61 / 120

TOPSPAN® 61 and TOPSPAN 120 light steelsections are strong and rigid, and maybe used for many applications as analternative to light gauge purlins andgirts of steel or timber.

Performance is maintained even in alapped situation, because the profilepermits a snug lap without the need tomodify the section’s shape.

These light steel sections can be usedin many commercial and domesticconstruction projects including sheds,garages and carports.

They are easily stored, transported andstacked.

The TOPSPAN range provides a versatilestructural solution from use as battensfor ceiling or roof construction to lightsteel sections for wall framing.

There’s a TOPSPAN product that’s rightfor your building application.

TOPSPAN 61 light steel sectionTOPSPAN 61TOPSPAN 61 is available in stock

and custom cut lengths and can be easily lapped. The performanceof TOPSPAN 61 is maintained even in a lapped situation because theprofile permits a precise, snug lapwithout the need to deform thesection’s shape.It can be used in many constructionprojects such as sheds, carports andgarages, or for racking, fencing orhandyman applications.Roll-formed from quality Australiansteel, TOPSPAN 61 is ZINCALUME® steelcoated for corrosion free long life. It won’t burn, warp, twist, splinter orrot and it won’t be attacked bytermites. TOPSPAN 61 is versatile,economical, easily handled andstored simply by stacking.

Material specificationsTOPSPAN 61 light steel sections are made from ZINCALUME® steel(aluminium/zinc alloy coated)complying with AS1397, G550,AZ150 (550 MPa minimum yield stress, 150 g/m2 minimumcoating mass).Thicknesses (BMT, mm) 0.75, 1.00Yield Strength (MPa) 550Coating Mass (g/m2) 150Mass (kg/m) 0.75 BMT 1.18

1.00 BMT 1.56

Safe load tablesThe tables give a practical andeconomical solution for mostdomestic buildings in non-cyclonicareas. Refer to table page 3.

Storing on-siteTOPSPAN 61 is delivered in strappedbundles. If not required forimmediate use, the bundles should be neatly stacked clear of the ground. When stacked theyshould be allowed to drain, shouldwetting occur. The bundles shouldnot be exposed in the open forextended periods. If unavoidable,protect from rain and moisture withwaterproof covers.TOPSPAN 61 sections will perform as specified if design, fabrication and fixing are in accordance with our recommendations and goodtrade practice.

Adverse conditionsZINCALUME® steel is suitable for mostexposure conditions. Consult yourlocal sales office for advice.

Installation options

Screw selectionFor fixing TOPSPAN 61 to supports andat lapped ends use Hex head selfdrilling and tapping screwsaccording to the following:

Steel supports (up to 2.0mm thick)No.12 - 14 x 20 mm long (TEKS)Timber Supports: Hard/softwoodNo.14 - 10 x 50 mm long (Type 17)At lapped ends: Refer to drawingabove for quantities and locations.

Lapping & CuttingThe best performance can beobtained by lapping sectionstogether as shown above.Recommended minimum lap lengthis 15% of span between rafters orsupports.

Cut TOPSPAN 61 using an abrasive discor metal cutting blade. Swarf andburred edges should be cleaned offon completion of cutting.

Fasteners: TeksNo.12 - 14 x 20 mm

Notes: The loads in the tables above are basedon test results where the following applies: 1. The safe loads have been determined from an

extensive test program, at BLUESCOPE LYSAGHT'sNATA registered testing laboratory.

2. The safe loads are uniformly distributed alongthe length of the TOPSPAN 61 and the loadsare applied through cladding, screw fixed toTOPSPAN 61.

3. The safe loads allow for connection capacity tothe supports. For cold formed steel supports,

NOTES:1. This document shall be read in conjuction with the TOPSPAN 61 Safe Load Tables (ref TS61safe-1558-11/96).2. The maximum support spacings have been based on the following pressure coefficients (for fully enclosed buildings):

Roofs: Cpe = -0.90 Cpi = +0.20 K1 = 1.5Walls: Cpe = -0.65 Cpi = +0.20 K1 = 1.5

3. The roof span details are based on non trafficable roof conditions in accordance with AS 1170.1 - 1989, and are only suitable for occasional maintenance loading.

4. The wind classifications (W28, W33, etc) are in accordance with AS 4055 - 1992, Wind Loads for Housing.5. All configurations are based on battens being fixed to steel (1.0mm BMT minimum) or timber supports,

as per the following fixing details:

Steel (up to 2.0mm BMT) No. 12 - 14 x 20mmTimber (hardwood and softwood) No. 14 - 10 x 50mmFasterners at end of laps No. 12 -14 x 20mm

Fasteners Legend for the Quick Selection Tables:

2 fasteners per support

4 fasteners per support

6. Laps shall be a minimum of 15% of the span (measured between fasteners) and fixed with 4 No. 12 - 14 x 20 Hex head self-drilling screws.

7. The minimum end bearing shall be 50mm.8. These charts may also be used for carport and verandah applications.

TOPSPAN 120 light steel sectionsTOPSPAN 120 light steel sections arean economical lightweight solutionto affix roofing and walling.Strong and rigid, TOPSPAN 120sections were originally developed tomeet rural market needs, howevertheir versatility now means they maybe used in many applications asalternatives to light gauge purlinsand girts (steel or timber).For flooring applications, pleasecontact your local BLUESCOPE LYSAGHT

office for advice.The performance of TOPSPAN 120 ismaintained even when lappedbecause the profile permits aprecise, snug lap without the needto deform the section’s shape.It can be used in many constructionprojects such as sheds, carports andgarages, or for racking, fencing orhandyman applications.Roll-formed from quality Australiansteel, TOPSPAN 120 is ZINCALUME® steelcoated for corrosion free long life. It won’t burn, warp, twist, splinter orrot and it won’t be attacked bytermites. TOPSPAN 120 is versatile,economical, easily handled andstored simply by stacking.Ease of UseDue to its innovative design, TOPSPAN

120 is much easier to work with thanC purlins. Its novel shape means itcan be mounted directly onto raftersor against columns without the useof cleats or bolts.It’s shape also allows TOPSPAN 120 tobe stacked for convenient storageand transportation.Material specificationsTOPSPAN 120 light steel sections aremade from ZINCALUME®

Topspan 120 - Carports/Awnings Quick Selection Chart

Notes for quick selection charts:1. A concerntrated live load of 1.1kN has

been allowed for in the tables2. A maximum deflection ratio of span/150

has been used.3. Maximum building dimensions are

as follows:Garage: Plan dimentions of 6.0m x 7.5m

Eaves height of 3.0m. Roof slope of 15°

Carport: Plan dimensions of 6.0m x 5.5mHeight of 3.0m. Roof slope of 5°

4. (S) Denotes a single span of TOPSPAN 1205. (D) Denotes a double span of TOPSPAN 1206. (L) Denotes a lapped span of TOPSPAN 1207. The numbers in cladding columns indicate

the required number of screw fastenersper sheet at supports for the selectedcladding. Clip fasteners are denoted by *

8. Double span configurations with a

capping detail at mid support may be replaced with a lapped double span.

9. Cladding is assumed to be continuousover at least two spans, thus cladding andfastener requirements are based on endspans. An allowance for local pressurefactore has been made.

10.The Inward and Outward DesignPressures include the loading from theself weight of cladding and TOPSPAN 120.

NOTES:1. The maximum support spacings have been on the following pressure coefficients (for fully enclosed buildings):

Roofs:Cpe = -0.9 Cpi = 0.2 Kl = 1.5

Walls: Cpe = - 0.65 Cpi = 0.2 Kl = 1.5

2. The roof span details are based on non trafficable roof conditions in accordance with AS 1170.1—1989, and is only suitable for occasional maintenance loading.

3. The wind classifications (W33, W41, etc) are in accordance with AS 4055—1992, Wind Loads for Housing.4. All configurations are based on battens being fixed to steel (1.9 mm BMT G450 minimum) or timber supports, as per the following

fixing details:
