Galvanized Sheet Classification

Galvanized sheets can be classified according to production and processing methods:

①Hot-dip galvanized steel sheet. The thin steel plate is immersed in the molten zinc tank, so that a thin steel plate with a layer of zinc is adhered to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel sheet is continuously immersed in the galvanized bath with molten zinc to make the galvanized steel sheet;

②Alloyed galvanized steel sheet. This kind of steel plate is also manufactured by hot dipping method, but immediately after it is discharged from the tank, it is heated to about 500°C to form an alloy film of zinc and iron. This kind of galvanized sheet has good paint adhesion and weldability;

③Electro-galvanized steel sheet. The galvanized steel sheet produced by the electroplating method has good workability. However, the coating is thinner, and the corrosion resistance is not as good as the hot-dip galvanized sheet;

④Single-sided and double-sided differential galvanized steel sheet. Single-sided galvanized steel sheet is a product that is galvanized on one side only. In welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of uncoated zinc on one side, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet;

⑤Alloy and composite galvanized steel sheet. It is a steel plate made of zinc and other metals such as lead and zinc alloys and even composite plating. This kind of steel plate not only has outstanding anti-rust performance, but also has good coating performance.
