First, single side and double side differential galvanized steel sheet. One side galvanized steel sheet, that is, only one side of galvanized products. In welding, coating, rust treatment, processing and other aspects, has better adaptability than the double side galvanized plate. In order to overcome the disadvantage of one side of the zinc coating, there is a kind of galvanized sheet, which is coated with a thin layer of zinc on the other side;
Second, hot dip galvanized steel sheet. The thin steel plate immersed in molten zinc bath, adhered to the surface of thin steel plate a layer of zinc. At present the main continuous galvanizing production process, which rolled steel continuously immersed in molten zinc plating bath is made of galvanized steel sheet;
Third, electro galvanized steel sheet. Manufacture of this kind of galvanized steel sheet by electroplating method has good workability. But the coating is thin, and the corrosion resistance is not as good as that of the hot dip galvanized sheet;
Alloy, composite galvanized steel sheet. It is made of zinc and other metals, such as lead, zinc alloy and even composite plated steel plate. This kind of steel plate not only has excellent anti rust performance, but also has good coating performance.
Alloying galvanized steel sheet. This kind of steel plate is made by hot dip method, but it is heated to about 500 degrees C immediately after it is produced, so that it can produce the alloy of zinc and iron. This kind of galvanized sheet has good sealing property and welding property;
