    Common problems and treatment methods in hot dip galvanized angle steel production

    Released on Jul. 01, 2020

    Hot dip galvanized angle steel, in short, is to soak the treated angle steel in the liquid zinc to make the zinc layer adhere to the surface of the angle steel, so as to meet the requirements of anti-corrosion. The hot-dip galvanized angle steel is widely used in electric power, communications, building materials, etc. because of its durable, strong coating toughness, time-saving and labor-saving characteristics. Next, we will introduce the common problems in the production and use of hot-dip galvanized angle steel Treatment method.
    1. Scratch phenomenon on the surface of hot-dip galvanized angle steel: in order to avoid the accumulation of technical lubricant or products and or dirt, it is necessary to carry out mechanical finishing on the scratch and other rough surface of hot-dip galvanized angle steel.

    2. The appearance of hot-dip galvanized angle steel presents the appearance of flux: the technology of using flux for welding includes craft welding, flux cored arc welding and submerged arc welding. These welding technologies will leave fine flux particles on the surface, which cannot be removed by general finishing methods. This particle will be the corrosion source of crevice corrosion. It is necessary to use mechanical finishing to remove the residual flux.
    The above is the summary of some common problems and treatment methods in the production and use of hot-dip galvanized angle steel for you, I hope to help you!
