Galvanized Steel Plate

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;

Product Description

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;


Full Cold Galvanizing Process:

Chemical degreasing → hot water washing → water washing → electrolytic degreasing → water washing → acid washing → rust removal → water washing → electrogalvanizing process → water washing → passivation → hot water washing → drying → quality inspection → packaging and sales
