Make allowance for thermal expansion or contraction for long length roofs at sheeting ends.

The equation ΔL = α x ΔT x L gives an indication of the sheeting extent or contraction (ΔL).

α = 12 x 10-6 (coefficient of linear expansion for steel).
ΔT = temperature change in °C.
L = sheet length in mm

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® steel 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 steel is prepainted steel for superior aesthetic qualities displaying a metallic sheen.

COLORBOND® Ultra steel 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 steel is 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, AS4040.0-1992 and AS4040.1-1992.

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.
