    Steel materials, the most widely used in industry, will corrode to varying degrees when used in the atmosphere, sea water, soil, building materials and other environments

    Anti-corrosion coating

    Steel materials, the most widely used in industry, will corrode to varying degrees when used in the atmosphere, sea water, soil, building materials and other environments. According to statistics, the annual loss of steel materials due to corrosion in the world accounts for about 1/3 of its total output. In order to ensure the normal use of steel products and prolong their service life, the anti-corrosion protection technology of steel has been widely valued

    Hot dip galvanizing
    Hot-dip galvanizing is one of the most effective means to delay the environmental corrosion of iron and steel materials. It is to immerse the cleaned and activated steel products in the molten zinc solution, and through the reaction and diffusion between iron and zinc, the zinc alloy coating with good adhesion is coated on the surface of iron and steel products. Compared with other metal protection methods, the hot-dip galvanizing process has incomparable advantages in the protection characteristics of the combination of physical barrier and electrochemical protection of the coating, the bonding strength of the coating and the substrate, the compactness, durability, maintainability and economy of the coating and its adaptability to the shape and size of the product

    Pre-galvanizing
    The difference between the processing technology of pre-galvanized steel pipe and hot-dip galvanizing is mainly in the raw materials used. The raw material of pre-galvanized steel pipe is mainly galvanized steel coil, which is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the molten zinc plating bath to make galvanized coil. After the galvanized coil is processed into steel pipe in the factory, it is no longer necessary to re-galvanize, but only need to supplement zinc to the welding part. The advantage of pre-galvanizing is that the zinc layer is more uniform and the appearance is more beautiful. Pre-galvanizing process is widely used in construction, machinery, solar energy and other fields because of its low plating cost, excellent protection characteristics and beautiful appearance
