Jinan Jintie Materials Co., Ltd. will continue to adhere to the concept of integrity-based mutual benefit and win-win, customer-centered, market-oriented, keep pace with the times, forge ahead, and build an excellent steel sales company for the ultimate goal. Target. Galvanized steel pipes are divided into cold-galvanized pipes and hot-galvanized pipes. The former has been banned, and the latter has been advocated by the state to be temporarily available. Hot-dip galvanizing pipe reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to in a hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Cold galvanizing is electro-galvanizing. The amount of galvanizing is very small, only /, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electro-galvanizing (cold plating). Our company is willing to go hand in hand with friends from all walks of life to create a beautiful and brilliant tomorrow.
