Definition of galvanized sheet

Galvanized steel sheet is to prevent the surface of the steel sheet from corrosion and prolong its service life. A layer of metal zinc is coated on the surface of the steel sheet. This galvanized thin steel sheet is called galvanized sheet.

Classification and use of galvanized sheet

1. Hot-dip galvanized sheet. Diffuse the thin steel plate into the molten zinc tank to make its surface adhere. At present, the continuous galvanizing process is mainly used for production, that is, the coiled steel plate is continuously immersed in the thin steel plate coated with a layer of zinc melted with zinc. Made of galvanized steel in tanks.

2. Alloyed galvanized steel sheet. This kind of steel panel also cannot be made with heat, but it is heated to about 500C immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability.

3. Galvanized steel plate. The galvanized steel panel manufactured by electroplating has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized panels:

4. Single-sided galvanized steel and double-sided differential galvanized steel. Single-sided galvanized steel sheet, that is, a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of one side without galvanizing, a galvanized panel coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized panel;

5. Alloy, composite galvanized steel plate. It is an alloy made of zinc and other metals such as lead and zinc or even a composite plated steel plate. This kind of steel plate not only has excellent antirust performance, but also has good painting performance
