galvanized steel sheet

1、 In order to prevent corrosion and prolong the service life of galvanized steel sheet, a layer of Dao metal zinc is coated on the surface of steel plate, which is called galvanized steel sheet.

2、 Different types of galvanized steel use different materials, such as.

1. Hot dip galvanized steel plate. A thin steel sheet with a layer of zinc adhered to its surface by immersing it in a molten zinc bath. At present, continuous galvanizing process is mainly used, that is, the rolled steel plate is continuously immersed in the bath with zinc melting to make galvanized steel plate;



2. Alloyed galvanized steel sheet. This kind of steel plate is also made by hot-dip method, but it is heated to about 500 ℃ immediately after it is out of the tank to form alloy coating of zinc and iron. The galvanized sheet has good coating adhesion and weldability;



3. Electro galvanized steel sheet. This kind of galvanized steel plate has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot dip galvanized sheet;



4. Single side plating and double side differential galvanizing steel plate. Single side galvanized steel sheet, that is, only one side galvanized products. It has better adaptability than double-sided galvanized sheet in welding, coating, antirust treatment and processing. In order to overcome the disadvantage of one side without zinc coating, there is another kind of galvanized sheet coated with thin layer of zinc on the other side;
