Span Tables
The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.
Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).
Wall spans consider resistance to wind pressure only.

The LYSAGHT® Roofing & Walling Installation Manual is a guide to the design and installation of steel roofing and walling manufactured by LYSAGHT®. We intend that it be used by all trades and professions involved with specifying and applying the wide range of our products. We refer only to genuine steel roofing and walling manufactured by us and marketed under our brand names. Our recommendations should only be used for our products because they are based on comprehensive testing of our profiles, base metal thicknesses (BMT) and material finishes.
Please be aware that in some Australian states cladding must be installed by licensed tradespeople. For correct specification and installation of LYSAGHT® roofing and walling products in cyclonic areas, please download the LYSAGHT® Cyclonic Area Design Manual for Steel Roofing, Walling & TOPSPAN®.
