Galvanized plate
Refers to the surface of galvanized sheet with a layer of zinc-plated steel. Zinc is often used in a cost-effective method of corrosion. Zinc production in the world about half are used for such processes
1. The definition of
Galvanized steel sheet is subjected to the surface to prevent corrosion, extending its life in the steel plate coated with a layer of metallic zinc, the zinc coated galvanized steel sheet as the board.
2. Classification and uses
According to production and processing methods can be divided into the following categories:
① hot-dip galvanized steel sheet. Thin steel plate will be immersed in the zinc melting tank to the surface adhesion of the thin layer of zinc plate. Zinc is mainly used for the production process, that is, to roll into a row of steel immersed in melting tanks are made of zinc-plated galvanized steel sheet;
② alloyed galvanized steel sheet. This plate is manufactured by hot dip method, but in a slot immediately after it is heated to about 500 ℃ to generate zinc and iron alloy coated. This Galvanized coatings have good adhesion and weldability;
Electro-galvanized steel sheet ③. Plating method used to create such a galvanized steel sheet has excellent workability. However, thinner coatings, corrosion resistance than hot dip galvanized plate method;
④ poor single-sided double-plated and galvanized steel sheet. Single-sided galvanized steel sheet, that is only in the side of galvanized products. In the welding, coating, rust-proof handling, processing, etc., than the two-sided galvanized sheet with better adaptability. Not coated on one side to overcome the shortcomings of zinc as well as a面涂another thin layer of zinc in zinc-plated board, that is, two-sided galvanized plate margin;
⑤ alloy, galvanized steel composite. It is made of zinc and other metals such as lead, zinc and even made of alloy steel plate into a composite plating. This plate not only has excellent anti-corrosion performance, and good performance of the coating.
In addition to the above five, there are color galvanized steel, galvanized steel sheet printing coating, such as galvanized steel sheet laminated PVC. Remains the most commonly used in hot-dip galvanized sheet.
