Classification And Application Of Galvanized Sheet
Jun 05, 2017

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

① Hot Dip Galvanized steel sheet. The thin steel plate is dipped into the zinc groove of the molten solution, so that the surface of the sheet is adhered with a thin layer of zinc. At present, the main use of continuous galvanizing process production, that is, the rolled steel plate continuously immersed in the molten zinc plating bath made of galvanized steel plate;

② Alloyed Galvanized Steel Sheet. This kind of steel plate is also made by hot-dip, but after the trough, it is immediately heated to about 500 Shan, so that its natural zinc and iron alloy film. This galvanized plate has good coating tightness and weldability;

③ Galvanized steel plate. It has good processability to make the galvanized steel sheet by electroplating. But the coating is thinner, the corrosion resistance is inferior to the hot dipping method galvanized plate;

④ Single-sided and double-sided galvanized steel plate. Single-sided Galvanized steel plate, that is only in one side galvanized products. In welding, coating, anti-rust treatment, processing, etc., has a better adaptability than double-sided galvanized plate. In order to overcome the shortcomings of one-sided uncoated zinc, there is a coating on the other side of the thin layer of zinc galvanized plate, that is, double-sided galvanized plate;

⑤ Alloy, composite galvanized steel plate. It is made of zinc and other metals such as lead, zinc alloy and even composite plating. This kind of steel plate has excellent antirust property and good coating performance.

In addition to the above five, there are color galvanized steel plate, printing coating galvanized steel plate, polyvinyl chloride laminated galvanized steel plate. But the most commonly used is still hot dip galvanized plate.

Galvanized steel plate can be divided into general use, house use, building outside the board, structural use, Li Plate, La and deep stamping galvanized steel plate.
