Span Tables
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, for further details Download LYSAGHT LONGLINE 305® (829 KB).
