Hot Products DX51D PPGI Galvanized Color Coated Corrugated Board for Roof Construction
One of the main properties of galvanized sheet is corrosion resistance. During the production process of galvanized sheets, a layer of zinc is plated on the iron substrate to form a protective film. This can effectively prevent oxidative corrosion caused by direct contact of the iron substrate with air and water.

EN10219 / BS1387 Hot Dip Galvanized ERW Round Steel Pipe
Galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
