Galvanized steel sheet is coated with a layer of metallic zinc on the surface of the steel sheet.It is often used to prevent corrosion of the steel and prolong its life. Galvanized steel is mainly divided into following two categories: 

1. Hot dip galvanized steel sheet. The steel sheet is immersed in a molten zinc bath to adhere a zinc-plated steel sheet to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel sheet; 

2. Alloyed galvanized steel sheet. This steel sheet is also produced by hot dip, but after it is discharged, immediately heat to about 500°C to form an alloy film of zinc and iron. This galvanized sheet has good adhesion and weldability of the coating.

 It is mostly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce industries, etc.
