 6.Galvalume steel sheet roofing materials

         Galvalume steel sheet is the preferred product for long-term resistance to atmospheric corrosion.It outlasts a galvanized coating of comparable thickness, and offers cut-edge protection that is not available with aluminum-coated sheet.This cut-edge protection means there is less rust-staining along sheared edges, at scratches, and other imperfections in the coating.Also,since the coating is so resistant to corrosion, it retains a very bright surface appearance when exposed to most conditions.These attributes make galvalume steel sheet the preferred material for roofing.The superior corrosion resistance of galvalume steel sheet is achieved by the presence of microscopic zinc-rich and aluminum-rich areas within the coating.The aluminum-rich areas,which corrode very slowly, provide the long-term durability while the zinc-rich areas,which corrode preferentially,provide galvanic protection.In most cases we offer only certain styles and profiles in the galvalume material but are adding new products daily.
