1. Single-sided plating and double-sided differential galvanized steel plate punching plate: single-sided galvanized steel plate, that is, a product that is only galvanized on one side. It has better adaptability than double-sided galvanized sheet in welding, painting, anti-rust treatment and processing. In order to overcome the shortcomings of uncoated zinc on one side, there is a galvanized sheet coated with a thin layer of zinc on the other side, that is, a double-sided differential galvanized sheet;
2. Hot-dip galvanized steel sheet: The thin steel plate punching net is immersed in the molten zinc tank, and the surface thereof is adhered to a zinc thin steel plate circular hole net. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel sheet;
3. Electro-galvanized steel sheet: The galvanized steel sheet produced by electroplating has good processability. However, the coating is thinner and the corrosion resistance is not as good as that of hot dip galvanized sheet;
4. Alloyed galvanized steel sheet: The steel plate punching is also made by hot dip method, but after the groove is taken out, it is heated to about 500 ° C immediately to form an alloy round hole mesh film of zinc and iron. This galvanized sheet has a good roundness of the adhesion and weldability of the coating.
5, alloy, composite galvanized steel: it is made of zinc and other metals such as lead, zinc alloy or even composite plated steel plate. This steel plate has both excellent rust resistance and good coating properties.
