A) hot-dip galvanized steel plate. Dip the sheet steel plate into the molten zinc tank and make the surface adhere to the sheet metal with a layer of zinc. At present, it is mainly produced by continuous zinc plating process, that is, the rolled steel plate is made of galvanized steel by continuous immersion in the molten zinc plating bath.
B) alloy galvanized steel plate. This kind of steel plate is made by hot dip method, but after the slot, immediately heated to a temperature of about 500 ℃, it make the generation of zinc and iron alloy membrane. The galvanized sheet has good coating tightness and weldability.
C) galvanized steel. This kind of galvanized steel plate made by electroplating has good machinability. But the coating is thin, corrosion resistance is not as good as hot-dip galvanized sheet;
D) single and double dip galvanized steel plate. Single side galvanized steel plate, 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 shortcoming of uncoated zinc on one side, there is another galvanized sheet coated with thin layer of zinc on the other side, i.e., two-sided differential galvanized sheet.
E) alloy and composite galvanized steel plate. It is made of zinc and other metals such as lead and zinc alloy and even composite plate. This kind of steel plate not only has excellent antirust performance, but also has good coating performance.
