BIG 6 profile clear PVC corrugated sheets are 1.3mm thick and 1080mm wide to give a 1000mm cover when overlapped. They conform to BS476 Pt 1 & BS4203 Pt 1. The BIG 6 profile is approximately twice the size of the conventional 3 inch corrugated profile and will match with sheets that were commonly used in the past to roof domestic garages and small industrial buildings.
