1 Hot Dip galvanized steel plate. The thin steel plate is immersed in the molten zinc groove and the surface is adhered with a thin layer of zinc. At present, the main use of continuous galvanizing process production, that is, the rolled steel plate continuously immersed in the molten zinc plating bath made of galvanized steel plate;

2 Alloy galvanized steel plate. This kind of steel plate is also made by hot-dip method, but after the trough, it is immediately heated to about 500 Shan, so that it produces zinc and iron alloy coated. This galvanized sheet has a good coating tightness and weldability.

3 Galvanized steel plate. It has good processability to make the galvanized steel sheet by electroplating. But the coating is thinner, the corrosion resistance is inferior to the hot dipping method galvanized plate;

4) single-sided and double-sided galvanized steel plate. Single-sided Galvanized steel plate, that is only in one side galvanized products. In welding, coating, anti-rust treatment, processing, etc., has a better adaptability than double-sided galvanized plate. In order to overcome the shortcomings of one-sided uncoated zinc, there is a coating on the other side of the thin layer of zinc galvanized plate, that is, double-sided galvanized plate;

5 alloy, compound galvanized steel plate. It is made of zinc and other metals such as lead, zinc alloy and even composite plating. This kind of steel plate has excellent antirust property and good coating performance.
