Hot-dip galvanized steel sheet. The thin steel sheet is immersed in a molten zinc tank to make a layer of zinc thin steel sheet adhered to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a plating tank with molten zinc to make a galvanized steel sheet;
Electro-galvanized steel sheet. This galvanized steel sheet made by electroplating has good processability. But the coating is thin and the corrosion resistance is not as good as hot-dip galvanized sheet;
