Corrugated Iron Roof Sheeting, also known as Classidek, is available in profile thickness ranges from 0.27mm to 0.80mm.

The corrugated sheets are available in 8.5/76 and 10.5/76 sizes, which means the sheet has 8.5; or 10.5 in the case of the 10.5/76 size; corrugations over the width of the sheet, with 76 mm between two consecutive curves. 8.5/76 sheets provide a coverage of 0.610m and 10.5/76 an effective coverage of 0.762 m. 10.5/76 roofing sheets provide the best of both worlds in that its rigidity and strength still compares favourably with alternative product ranges but at a more cost effective price range due to the availability of a thinner gauge.

Corrugated Iron Roof Sheeting is used as roof cladding, to protect buildings from weather extremes. Corrugated roofing sheets are predominantly targeted at the domestic market. Because of its affordability, corrugated is also the roofing solution for low cost housing projects.
