Caitu: color-coated (hot-dip zinc caitu) is the molten metal and the reaction of the iron matrix alloy layer, so that the substrate and coating combination of both. Color-coated steel supply is first pickled, in order to remove iron steel surface after pickling color coated by mixing an aqueous solution of ammonium chloride or zinc chloride aqueous solution tank or ammonium chloride and zinc chloride Cleaning the exercise price, and then into the hot dip tank. HDG has a uniform coating, strong adhesion continues color steel manufacturer, long life and other advantages. The thickness of the clean room is used generally below 0.5mm  were 0.5mm, 0.45mm, 0.4mm wall and large span batts to ensure the strength and stiffness of 0.5mm color steel should be used in a small shed span  board can be 0.45mm, 0.4mm. Color-coated substrate with the molten bath complicated physical and chemical reactions color steel, corrosion-resistant compact form of zinc-iron alloy layers. Alloy layer and the pure zinc layer, steel substrate integrated. So its resistant to corrosion, make big spangle spangles formed by crystallization bumps and different gloss obtain smooth unification. Color-coated galvanized steel and heat it to the substrate steel firm structure, light steel flexible structure in line with Building Code of surface quality, light steel structure are rust paint treatment, the volume of color-coated composite, coating, etc. finished processing adversely affected. 1998-2002, the domestic production of slow growth in electricity caitu where selling color steel, from 17 million tons to 400,000 tons Cai Gang Vol wholesale price, HEPA is appropriate stainless steel frame, beautiful and clean, perforated metal mesh plate with aluminum paint, no rust dust free, appropriate cleaning. Color volume wholesale price, Jinhong Run steel (certified), Anyang Color volume provided by the Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry. Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry (www.bxjhr.com) (www.bxjhr.com) is an industry leader in Shandong Binzhou, plate (with) wood, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Jinhong Run steel leader with the staff warmly welcome all inquiries negotiations to create a better future Jinhong Run steel.
