Zhumadian galvanized steel Zhengzhou Bao Steel Co., Ltd. is an agent of steel Friends of Henan Province, located in Zhengzhou City, South Fourth Ring Kinmen steel market, the main business YHI pipe, galvanized pipe, and plastic composite pipe galvanized Tianjin Friends tubes and plastic composite pipe diameters DN15-DN300, Friends of pipe wall thickness of 1.8-5.75 Handan and galvanized pipe diameter of DN15-DN200, spiral pipe wall thickness of 1.5-6 Handan Friends, 219-1220 diameter, wall thickness of 6 -20 spot wholesale and retail, please contact the inquiry to discuss cooperation! ! Main specifications galvanized hot dip galvanized steel pipe are: 4 points, 6 points, 1 inch, 1.2 inch, 1.5 inch, 2-inch, 2.5-inch, 3-inch, 4-inch, 5-inch, 6-inch, 8-inch, 10-inch, galvanized square tube production specifications are 20 * 20 to 600 * 600 and so on, producing a variety of greenhouses galvanized pipe. Hot dip galvanized steel products are mainly used for large curtain wall engineering, traffic electrical engineering, engineering applications such as greenhouses. Galvanized pipe, also known as galvanized steel, hot galvanized and galvanized two electricity, hot dip galvanized galvanized thickness, with coating uniformity, strong adhesion, long life and other advantages. Low cost electric galvanized surface is not very smooth, corrosion resistance itself a lot worse than the galvanized pipe. Cold galvanized steel sub-plated pipes, hot dip tube, the former has been disabled, which is also the state to promote temporary use. Is the molten metal and iron-base alloy layer produced by the reaction, so that the substrate and coating combination of both. Hot dip galvanized steel is first pickled, the steel surface in order to remove iron oxide, after pickling, cleaning by a mixed aqueous solution of ammonium chloride bath or an aqueous solution of zinc chloride or ammonium chloride and zinc chloride, and then into hot dip tank. Has galvanized coating uniformity, strong adhesion, long life and other advantages. Cold galvanizing is galvanized, galvanized rarely, and only 10-50g / m2, its own hot galvanized pipe corrosion resistance than a lot of difference. Regular galvanized pipe manufacturers, in order to ensure the quality, most do not use galvanized (cold plate). Only those small, outdated equipment and small businesses using electro-galvanized, of course, their prices are relatively cheaper. Henceforth allowed to use galvanized pipe for cold water, gas pipes. Steel substrate and the molten bath complicated physical, chemical reaction, the formation of corrosion-resistant compact structure of zinc-iron alloy layers. Alloy layer and the pure zinc layer, integrated steel substrate. So its resistant to corrosion. Zinc plating layer is independent layered zinc coating and steel substrate. Thin layer of zinc, zinc layer simply attached to the steel substrate, easily. So the poor corrosion resistance.
