how ICS curved roof sheets are made

This is how Industrial cladding systems of Newcastle upon Tyne crimp curve their roofing sheets, as any sheeting contractor knows accurate curves are very important as during the installation there is no give in the sheet, making it difficult to keep straight lines across the building, our curves are perfect every time with this servo driven curving machine, note: at the centre there is a pressed water channel to let the water escape from the top of the curve, without this water will pool and collect dirt and would need cleaning every few months
