Immerse the galvanized sheet into the molten zinc bath to make it adhere to a thin steel plate coated with zinc. Now it is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the bath with melted zinc to make galvanized steel plate.
This kind of Galvanized sheet is also made by hot dip method, but it is heated to about 500 ¡æ immediately after being out of the bath, so that it can generate zinc and iron alloy films. This galvanized sheet has excellent coating tightness and weldability. Electro galvanized steel sheet. The galvanized steel sheet produced by electroplating has excellent processability. However, the coating is thin and the corrosion resistance is not as good as that of hot-dip galvanized sheet; Single side and double side differential galvanized steel sheets. Single side galvanized steel plate, that is, products that are galvanized only on one side. It has better adaptability than double-sided galvanized sheet in welding, coating, anti rust treatment, processing, etc. In order to overcome the defect that one side is not coated with zinc, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side, namely, double-sided differential galvanized sheet, alloy and composite galvanized sheet. It is made of zinc and other metals such as aluminum, lead, zinc and other alloys and even composite plated steel plate. This kind of Galvanized sheet not only has excellent rust prevention function, but also has excellent painting function.
In addition to the above five types, there are also colored galvanized steel sheets, printed galvanized steel sheets, PVC laminated galvanized steel sheets, etc. But now the most commonly used is still hot-dip galvanized sheet.
