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 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;

PRODUCT PARAMETERS

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;


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
