Material Specification

Next generation ZINCALUME® aluminium/zinc/ magnesium alloy coated steel complies with AS1397:2011 G550, AM125 (550 MPa minimum yield stress, 125 g/m2 minimum coating mass)

  • COLORBOND® is prepainted steel for exterior roofing and walling. It is the most widely used. The painting complies with AS/NZS 2728:2013 and the steel base is an aluminium/zinc alloy-coated steel complying with AS 1397:2011. Minimum yield strengths are G550 (550MPa), or G300 (300MPa) depending on profile. Minimum coating mass is AM100 (100g/m2)
  • COLORBOND® Metallic is prepainted steel for superior aesthetic qualities displaying a metallic sheen.
  • COLORBOND® Ultra is prepainted steel for severe coastal or industrial environments (generally within about 100-200 metres of the source). The painting complies with AS/NZS 2728:2013 and the steel base is an aluminium/ zinc alloy-coated steel complying with AS 1397:2011. Minimum coating mass is AM150 (150g/m2)
  • COLORBOND® Stainless is a pre-painted steel and is used for severe and coastal environments. The painting complies with AS/NZS 2728:2013 and the steel base is a stainless steel complying with AISI/ASTM Type 430; UNS No. S43000.

Span Table

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 pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3.

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®.
