①Hot dip galvanized sheet. The sheet steel is immersed in a molten zinc bath, and a sheet of zinc is adhered to its surface. At present, it is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in a plating tank with zinc melted to make cold-rolled steel plate;
② Knowledge of alloyed cold-rolled steel sheets. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized sheet has good paint adhesion and weldability;
③ Knowledge of electric cold rolled steel plate. The knowledge of manufacturing this cold-rolled steel sheet by electroplating has good workability. However, the coating is thin, and the corrosion resistance is not as good as that of the hot-dip galvanized sheet;
④ Knowledge of single-sided plated and double-sided differential cold-rolled steel plates. Knowledge of single-sided cold-rolled steel sheets, that is, products that are galvanized on only one side. 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 galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet; Zinc sheet, cold rolled steel sheet, galvanized iron sheet, galvanized sheet price, white iron sheet
⑤Alloy and composite cold-rolled steel plate knowledge. It is made of zinc and other metals such as lead and zinc to make alloys and even composite plated steel sheets. This kind of steel plate has both excellent anti-rust properties and good coating properties.
