Wholesale Price High Quality Sgc490 6160 Z280 Prepainted Galvanized Steel Corrugated Sheet for Roof Construction Material
Product Description
1. Hot dip galvanized steel sheet. dip a sheet of steel into a molten zinc bath so that it adheres to a sheet of zinc. 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 sheet. This steel plate is also made by hot dip, but immediately after the trough, it is heated to about 500ºC, so that it generates an alloy film of zinc and iron. This galvanized sheet has good coating tightness and weldability;
This galvanized steel plate has good machinability by electroplating.
But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet;
3. Single side plated and double side 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;
4. Alloy, composite galvanized steel plate. It is made of zinc and other metals such as lead, zinc alloy or composite plated steel plate. This kind of steel plate has excellent anti-rust performance and good coating performance.
