Span Table

The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992. Supports must not be less than 1mm BMT.

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 figures relate only to buildings 10m or less in height and located in sheltered or exposed suburban areas or sheltered rural areas only

Were there previously two versions of INTEGRITY® available?

The INTEGRITY® profile was made in two versions up until August 2001. These were the INTEGRITY® 820 (with a cover width of 820mm and a rib height of 48mm) and INTEGRITY® 890 (with a cover width of 890mm and a rib height of 40mm). While INTEGRITY® 890 was discontinued in August 2001, INTEGRITY® 820 is still available.

How is INTEGRITY® 820 fixed?

INTEGRITY® 820 is fixed through the ribs using screws, in the same way as many of the LYSAGHT® claddings. However, when fixing, a metal sealing washer is included to give the INTEGRITY® 820 its high performance.

What is cladding and how does it relate to roofing and walling?

Cladding is a collective term for any sheeting that covers a building, whether it be on the roof of the building, or on the walls. Roof cladding is made from thicker steel and is rolled to a profile capable of supporting roof traffic*. In most cases, these roof claddings can also be used for walling as well. Wall cladding is made from thinner steel, rolled to a less rigid profile. They are generally not capable of supporting roof traffic, prohibiting their use as roofing.

*Some roofing is designed to be non-trafficable. Please consult the span and capacity tables of the cladding for further details.

Colour Range

LYSAGHT INTEGRITY® 820 is available in a limited range of COLORBOND® steel colours and in unpainted ZINCALUME® steel.
