Classification Of Galvanized Sheet
Aug 15, 2017

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

① Hot Dip Galvanized steel plate. The thin steel plate is immersed in the molten zinc groove and the surface 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 method, but after the trough, it is immediately heated to about 500 ℃, so that it produces 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 plate by electroplating. But the coating is thinner, the corrosion resistance is inferior to the hot dipping method galvanized plate;

④ single-sided Plating and double-sided zinc 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 another coating on the other side of the thin layer of zinc galvanized plate, that is, double-sided galvanized plate;

⑤ alloy, clad galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc and other alloy and even composite plating. The 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.
