    Factory Supplier Hot Dip Galvanized Round Steel Pipe For Construction

    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.

    With more than 10 years steel exporting experience to more than 100 countries, we have gained great reputation and lots regular clients.

  • Galvanized Square Steel Tube in Multiple Sizes

    Galvanized Square Steel Tube in Multiple Sizes

    Galvanized square pipe refers to a steel pipe coated with a layer of zinc on the surface of ordinary steel pipes. The zinc layer can form a protective film on the surface of the steel pipe, which can effectively extend the service life of the steel pipe and improve the corrosion resistance of the steel pipe.

Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in the north adopt the zinc replenishment process of galvanized belt direct coil pipe.

    Cold galvanized pipe: galvanized pipe cold galvanized is electric galvanized, galvanized amount is very small, only 10-50 grams per square meter, its own corrosion resistance is much different than hot galvanized pipe. Regular galvanized pipe production plants, for quality, most do not use electric galvanizing (cold plating). Only those small enterprises with obsolete equipment use electric galvanizing, of course, the price is relatively cheap.

    Factory Wholesale Price Carbon Steel Pipe Square Hollow Section Galvanized Shs Steel Pipe

    Galvanized square pipe  is electric galvanized, galvanized amount is very small, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electric galvanizing (cold plating). Only those small enterprises with obsolete equipment use electric galvanizing, of course, their prices are relatively cheap. The Ministry of Construction has formally announced the elimination of cold galvanized pipes with backward technology, and it is not allowed to use cold galvanized pipes as water and gas pipes. The galvanized layer of cold galvanized steel pipe is an electric coating, and the zinc layer is independently layered with the steel pipe matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold galvanized steel pipes as water supply pipes.

    Galvanized square pipe  is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily. In the 1960s and 1970s, the developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. China’s Ministry of Construction and other four ministries and commissions have also issued a document to prohibit galvanized pipes as water supply pipes from 2000, the cold water pipes in the new community have rarely used galvanized pipes, and the hot water pipes in some communities use galvanized pipes. Hot-dip galvanized steel pipe has a wide range of applications in fire, power and highway.

  • GI Pipe Galvanized Steel Pipe Galvanized Tube For Greenhouse Frame

    GI Pipe Galvanized Steel Pipe Galvanized Tube For Greenhouse Frame

    Galvanized seamless pipes is a galvanized steel pipe. Its main feature is to form a layer of zinc on the surface of the steel pipe to improve the corrosion resistance of the steel pipe. The production process of galvanized pipe is usually to immerse the steel pipe in molten zinc so that its surface is evenly covered with a layer of zinc. This treatment method makes the galvanized pipe have better corrosion resistance and can be used for a long time in humid and corrosive environments.
