1, hot dip galvanized steel plate. The sheet steel is immersed in the melted zinc tank so that the surface is adhered to a layer of zinc sheet steel. At present, it is mainly produced by continuous galvanizing process, that is, continuous immersion of rolled steel plates in melting zinc plating tanks to make galvanized steel plates

2, alloyed galvanized steel plate. This steel plate is also made by hot dipping, but after the tank is out, it is immediately heated to about 500 ° C to generate an alloy film of zinc and iron. This galvanized sheet has good coating adhesion and weldability

3, fingerprint resistant galvanized steel plate. Fingerprint-resistant galvanized steel plate is added to the ordinary electrolytic plate on the basis of a fingerprint-resistant treatment, can resist sweat, generally used in the parts without any treatment, the brand is SECC-N. Ordinary electrolytic plate and phosphating plate and passivation plate, phosphating is more commonly used, the brand is SECC-P, commonly known as p material. Passivated plates can be oiled or unoiled.

4, electric galvanized steel plate. The galvanized steel plate made by electroplating has good workability. However, the coating is thin and the corrosion resistance is not as good as that of hot-dip galvanized sheet.

Galvanized steel plate is a surface plated with a layer of zinc steel plate, there are many categories of galvanized steel plate, can be divided into hot dip galvanized steel plate, alloyed galvanized steel plate, fingerprint resistance galvanized steel plate and electric galvanized steel plate
