Product Overview
Corrugated roofing sheet is cold formed from hot dip galvanized coil into a 25-35 mm wave with an even pitch, so sheets lap peak-to-peak and valley-to-valley and, with self-drilling screws and sealing washers, give a watertight roof. The coating runs 60-275 g/m2, which in coastal and industrial atmospheres means 15-25 years of service. Sheets can be produced to the exact roof slope length, cutting site waste and trimming time.
