To extend its service life, Galvanized steel sheet is designed for corrosion resistance,which surface coated with a layer of metal zinc to prevent
the steel sheet’s surface from corrosion.
As per the production and processing methods can be divided into the following categories:
1.Hot dipped galvanized steel sheet
Let the sheet into fusible zinc bath to make surface adhesion with a layer of zinc. Adopt to continuous galvanizing process mainly,it will form the
galvanized steel sheet.
2.Alloy-galvanized steel sheet
This kind of steel sheet is also made by method of hot dip, after the slot,it will be heated about 500 ℃ immediately for making the generation of
zinc and iron alloy membrane,so the sheet will be more sex and weldability.
3.Electro-zinc coated sheet
The sheet will be more good workability through the method of Electro-
zinc coated. But the coating is thinner, the corrosion resistance is less than the method of hot dipped galvanized sheet.
