What is Galvalume Steel Coil
The galvalume steel coil, also called aluzinc steel coil, is made by cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.5% zinc and 1.5% silicon at 600 °C. Similar to galvanized steel, galvalume steel is produced by a hot-dip process. It combines the physical protection and high durability of aluminum and the electro chemical protection of zinc.
