Galvanized sheet
Introductions of Galvanized sheet(GI)
Galvanized sheet is push after annealing treatment of cold-rolled steel pickling, the removal of surface oxide, repass containing zinc chloride and ammonium chloride solvent tank, and then into the molten zinc galvanized trough, and then on to passivation, oil and other post-processing stage of zinc coated steel

The main use of galvanized sheet
Galvanized steel sheet according to the purposes and can be divided into general use, roof, construction of the lateral plate, structure, corrugated board, stretching and deep drawing, etc.
Mainly engaged factories of Galvanized sheet
Shanghai Baosteel , Beijing shougang, Changshu branch wong, Guangdong han jiang, Tianjin profit source, Shandong hua LuWeiYe,, Shaanxi China LuWeiYe
Characteristics of galvanized sheet
Divided into the surface of galvanized sheet structure:
The normal zinc(Z), Minimized Spangle (X), The finishing zinc(GZ). Galvanized steel surface has been designed or leaves of zinc crystal decorative pattern, the galvanized layer is firm, has excellent corrosion resistance, and good welding performance and cold forming performance.
According to the production and processing methods can be divided into the following categories
Hot dip galvanized steel. The steel plate into dissolved in the zinc bath, make its surface adhesion of a layer of zinc sheet steel. At present mainly adopts continuous galvanizing process, namely the continuous leaching rolls of steel plate in the dissolution of zinc plating tank made of galvanized steel plate;
Electric galvanized steel. Electricity galvanized manufacturing this kind of galvanized steel has good workability, but with thin coating, corrosion resistance is better than the method of hot dip galvanized sheet
Single and double difference galvanized steel plating. Single galvanized steel, that is, only in a galvanized products. During welding, coating, antirust processing, processing, etc., two-sided galvanized sheet better adaptability. In order to overcome the single side not the shortcoming of zinc coating, and one in the other side is coated with a thin layer of zinc galvanized sheet, namely the two-sided galvanized sheet
Alloy, composite galvanized steel. It is made from zinc and other metals such as lead, zinc alloy and composite plating of steel plate. This steel has excellent rust resistance, and good coating performance. Apart from the above four, color galvanized steel plate, printing and coating of galvanized steel sheet, JuAnYiXi laminated galvanized steel sheet, etc. But still by far the most commonly used for hot dip galvanized sheet
