①Galvanized Steel Coil. Dip the thin steel plate into the molten zinc tank to make the thin steel plate with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production; that is, the coiled steel plate is continuously immersed in a galvanizing tank with the molten zinc to make a galvanized steel plate;
②Alloyed galvanized steel plate. This kind of steel panel is also made by the hot dip method, but it is heated to about 500℃ 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;
③Electro-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;
④Single-sided galvanized steel and double-sided 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 a double-sided galvanized sheet. In order to overcome the shortcomings of one side without galvanizing, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized sheet;
⑤ alloy, composite galvanized steel. 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 has not only excellent antirust performance but also has good painting performance.
