Galvanized steel coil is made of carbon steel coated in zinc utilizing the hot-dip process. The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition.
Aluminum zinc coated steel plate(Galvalume steel coil) has many excellent characteristics: strong corrosion resistance and beautiful zinc flowers on the surface. It can be used as building exterior plate.
