What is the classification of Galvanized Steel Sheet?

Galvanized sheet refers to a thick Steel Plate with a layer of zinc plated on the surface. Hot-dip galvanizing is an economical and reasonable anti-rust treatment method that is often selected. About half of the world's zinc production is used as such a process. So what is the classification of galvanized sheet, what the galvanized Steel Sheet manufacturer can tell you.

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

①Hot-dip galvanized steel sheet. A cold-rolled steel sheet in which a layer of zinc is adhered to the surface by infiltrating the cold-rolled steel sheet into the molten zinc bath. At this stage, the key is to use continuous hot-dip galvanizing process to manufacture, that is, continuous immersion of thick steel plate in a plate into a plating tank with molten zinc to make Galvanized Steel Plate;

② Fine-grained reinforced galvanized steel sheet. This type of thick steel plate is produced by the hot dip method, but immediately after it is out of the groove, it is heated to about 500 ° C to convert it into an aluminum alloy plastic film of zinc and iron. This type of galvanized sheet has excellent adhesion of architectural coatings and electric welding;

③ Electro-galvanized steel sheet. The production of this type of galvanized steel sheet by electroplating has excellent process performance. However, the coating is thin, and the corrosion resistance is not as good as that of hot-dip galvanized sheet;

④Single-sided and double-sided galvanized steel. Single and double-sided galvanized steel sheets, that is, products that are hot-dip galvanized on only one side. In electric welding, spraying, rust prevention, production and processing, etc., it has stronger adaptability than double-sided galvanized sheet. In order to get rid of the defect of uncoated zinc on both sides, there is another kind of galvanized sheet coated with chromatographic zinc on the other side, that is, galvanized sheet with difference on both sides;

⑤ Aluminum alloy, composite galvanized steel sheet. This is a thick steel plate made of aluminum alloy or even composite plated with zinc and other metal materials such as aluminum, lead, zinc, etc. This kind of thick steel plate not only has extraordinary anti-rust treatment characteristics, but also has excellent spraying characteristics; in addition to the above five kinds, there are also colorful galvanized steel plates, clothing printing sprayed galvanized steel plates, polyethylene laminated galvanized steel plates, etc. But at this stage, the most common is still hot-dip galvanized sheet.
