Classification of galvanized sheets

According to the production and processing methods, it can be divided into the following types:

①Hot-dip galvanized cold-rolled steel plate. The cold-rolled steel plate is infiltrated into a molten zinc bath so that a layer of zinc adheres to the surface of the cold-rolled steel plate. At present, it mainly adopts the continuous hot-dip galvanizing process, that is, the coils of cold-rolled steel sheets are continuously immersed in a plating bath containing molten zinc to make galvanized sheets; ② Fine grain improves galvanized sheet. This type of cold-rolled steel is also produced by the hot-dip method, but after coming out of the tank, it is heated to about 500°C to convert it into an aluminum film of zinc and iron. This type of galvanized sheet has high-quality industrial paint adhesion and arc metal laser welding equipment, arc metal laser welding machine, arc laser welding, arc welding, electric welding;

③Electro-galvanized sheet. This kind of galvanized sheet produced by electroplating method has high quality technical parameters. However, the coating is thin and its corrosion resistance is not as good as that of hot-dip galvanized sheets;

④ Front and back plated and double-sided galvanized plates. Front and back galvanized sheets are products that are hot-dip galvanized on only one side. In terms of arc metal laser welding equipment, arc metal laser welding machine, arc laser welding, arc welding, spraying, anti-rust treatment, processing, etc., it has stronger adaptability than double-sided galvanized sheets. In order to deal with the defect that the front and back sides are not coated with zinc, there is another type of galvanized sheet that is coated with chromatographic zinc on the other side, that is, a double-sided galvanized sheet;

⑤Aluminum profiles and composite galvanized sheets. It is a cold-rolled steel plate made of zinc and other metal polymer materials such as aluminum, lead, zinc, etc., or even composite plated. This type of cold-rolled steel plate has both extraordinary anti-rust treatment properties and high-quality spray coating properties;

In addition to the above five types, there are also colorful galvanized sheets, printing spray galvanized sheets, high-density high-density polyethylene laminated galvanized sheets, etc. But at present, hot-dip galvanized sheets are still the most widely used.
