GALVALUME STEEL SHEETS/COILS
Galvalume Steel Sheets are widely used in roofing and cladding. It is a kind of steel sheet with zinc-aluminum alloy coating, the product of Galvalume steel forming the protection layer and ordinary steel sheets. It is a type of steel sheet metal that contains a coating of zinc – aluminum. Galvalume protects steel from corrosion in the same way that galvanized steel does, although galvanized sheets are coated with zinc alone. For more information, contact us!
