4m-12m Length Hot Dipped Galvanized Mild Steel

Galvanized Steel Sheet is to prevent the Steel Plate surface from corrosion to extend its service life, in the steel plate surface coated with a layer of metal zinc, the zinc coated steel plate are called galvanized sheet.

1. Hot dip galvanized Steel Coil. 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 coil. 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 coil. 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 coil. 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; 5. 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;
