Alloyed galvanized steel plate: This special tubular steel plate is made by hot dip, but immediately after the tank, it is heated to about 500℃, so that it produces zinc and iron alloy coating. The galvanized sheet has good coating adhesion.
Single-sided and double-sided galvanized steel: Single-sided galvanized steel, only on one side of the galvanized product. In welding, coating, rust treatment, processing and other aspects, has better adaptability than double-sided galvanized board. In order to overcome the disadvantage of one side without zinc, there is another coated with a thin layer of zinc galvanized sheet, that is, double-sided difference galvanized sheet SGCC: A sheet of steel dipped in a molten zinc bath to make the surface adhere to a layer of zinc. At present, the main use of continuous galvanized production process, that is to roll the steel continuous dip in the molten zinc plating tank made of galvanized steel 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 special tubular steel plate not only has excellent rust resistance, but also has good coating performance SECC: This kind of special-shaped galvanized steel plate has good fabricability by electroplating. But the coating is thin, corrosion resistance as hot dip galvanized sheet.
In addition to the five kinds, there are color galvanized steel plate, printing coating galvanized steel plate, PVC laminated galvanized steel plate. Galvanized sheet can be divided into general use, roof use, building outer board with, structure with, tile ridge board with, stretch with and deep drawing with galvanized steel plate.
