When using the corrugated iron sheet in a wall cladding application, there is choice between 12 gauge x 25 mm timber fix screws, when fixing into timber. Othewise, 10 gauge x 16mm will do the trick when fixing into steel.These screws are shorter as they are fixed into the pan (or valley) of the corrugation. "Cover of roofing sheet" : is the measured amount each sheet will cover (including side lap) when layed in position on the roof. IE the cover of a corrugated roof sheet is 760mm or .76 metre. Please consider both resistance to wind pressure and foot traffic for roofing spans. 


Please consider a couple of factors when deciding whether you need .42bmt or .48bmt sheets as roof covering:

Your batten spacing
How often the roof will be walked upon

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).
