Dissolution Process Of Galvanized Steel Sheet Oct 27, 2017

Galvanized steel plate is to prevent corrosion on the surface of steel plate, prolong its service life, on the surface of the steel plate coated with a layer of metal zinc, this zinc-coated thin steel plate known as galvanized plate. Zinc plating is an economical and effective antiseptic method which is often used. About half of the world's zinc production is used in this process.Galvanized Steel Sheet

Hot Dip Galvanized steel sheet. 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 into the galvanized steel plate; alloying galvanized steel plate. 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 coated. This galvanized sheet has a good coating tightness and weldability.Galvanized Steel Sheet

Galvanized steel plate with single-sided plating and double-sided difference. 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, Alloy, composite galvanized steel plate. It is made of zinc and other metals such as lead, zinc alloy and even composite plating. This kind of steel plate has excellent antirust property and good coating performance.Galvanized Steel Sheet 

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.Galvanized Steel Sheet

Galvanized sheet should have a good appearance, no harmful to the use of product defects, such as no plating, holes, rupture and dross, more than plating thickness, abrasions, chromic acid dirt, white rust and so on. Foreign standards on the specific appearance of defects are not very clear. Some specific defects should be specified in the contract when ordering.Galvanized Steel Sheet
