Hot Dipped 1.2mm Thickness 12 14 16 18 20 22 24 26 28 Gauge GI Plain Metal Sheet Galvanized Steel Sheet
According to the production and processing methods can be divided into the following categories:
Hot dip galvanized steel plate. A sheet of steel is dipped into a molten zinc bath so that it adheres to a sheet of zinc on its surface. At present, the continuous galvanizing process is mainly used for production, that is, the steel plate into a roll of continuous immersion in the melting of zinc plating tank made of galvanized steel plate;
② Alloyed galvanized steel plate. This steel plate is also made by hot dip, but immediately after the trough, it is heated to about 500℃, so that it generates an alloy film of zinc and iron. This galvanized sheet has good coating tightness and weldability;
③ Electric galvanized steel plate. The production of galvanized steel plate by electroplating has good machinability. But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet;
④ Single-sided plating and double-sided difference galvanized steel plate. Single-sided galvanized steel, that is, galvanized only on one side of the product. In welding, coating, rust treatment, processing and other aspects, it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of single side not coated with zinc, and a galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided difference galvanized sheet;
Alloy, composite galvanized steel plate. It is made of zinc and other metals such as aluminum, lead, zinc alloy and composite plated steel plate. This steel plate has excellent anti-rust performance and good coating performance;
In addition to the above five, there are color galvanized steel, printing coated galvanized steel, PVC laminated galvanized steel and so on. But the most commonly used is still hot dip galvanized sheet.
