Classification And Analysis Of Galvanized Steel Jul 03, 2017

       Galvanized steel, refers to the ordinary carbon construction steel through the galvanized process can effectively prevent corrosion rust and prolong steel service life, including galvanized zinc plating zinc and hot dip galvanizing. Commonly used in building facades, such as glass curtain wall, marble curtain wall, aluminum curtain wall to do columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air construction steel known as galvanized steel, galvanized zinc and hot dip galvanizing.Galvanized Steel
       Category: Hot-dip galvanized pipe is to make the molten metal and iron-based body reaction to produce alloy layer, so that the matrix and the coating both together. Hot Dip Galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed water solution tank in the cleaning, and then into the hot dip bath. Hot-Dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Hot-dip galvanized steel pipe substrate and molten plating liquid occur complex physical and chemical reaction, forming a corrosion-resistant structure of a dense zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. So its corrosion resistance is strong. The cold galvanized pipe is galvanization zinc, the galvanization quantity is very few, only 10-50g, its own corrosion-resistant specific heat galvanization tube difference is many. Regular galvanized pipe manufacturers, in order to ensure the quality, most do not use zinc plating (cold plating). Only those small, old-fashioned equipment used galvanization zinc, of course their prices are relatively cheap. At present, the Ministry of Construction has been formally below, the elimination of technology behind the cold galvanized pipe, the future is not allowed to use cold galvanized pipe for water, gas pipe. The galvanized layer of the cold galvanized steel pipe is electroplated layer, and the zinc layer and the steel pipe matrix are separated. The zinc layer is thinner, and the zinc layer is simply attached to the steel tube matrix, which is easy to fall off. So its corrosion resistance is poor. In newly-built dwellings, the use of cold galvanized steel pipes is prohibited.Galvanized Steel
      Often said galvanized pipe, galvanized pipe use now gas, heating the kind of iron pipe is galvanized pipe, galvanized pipe as a water pipe, the use of a few years later, the tube produced a large number of rust, the outflow of yellow water not only contaminated sanitary ware, but also mixed with a smooth wall breeding bacteria, rust caused by heavy metal content in water, serious harm to human health Galvanized Steel
