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 adhere to its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel sheet is continuously immersed in a molten zinc plating tank to make a galvanized steel sheet;
Electrogalvanized steel sheet. This galvanized steel sheet made by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as that of hot-dip galvanized steel sheet;
