    Galvanized Square Steel Pipe Rectangular Steel Tubes

    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 the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the in the hot dip bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The steel tube substrate and the molten plating solution undergo compl...

    Hot Dipped ASTM A106 GR.B Galvanized Steel Pipe Steel Tubes

    Galvanized steel pipes are divided into hot galvanizing and electro galvanizing. The hot galvanizing layer is thick, the cost of electro galvanizing is low, and the surface is not very smooth.

  • ASTM A53 Hot Dipped Galvanized Steel Pipe Steel Tubes

    ASTM A53 Hot Dipped Galvanized Steel Pipe Steel Tubes

    Hot Dipped Galvanized Steel Pipes is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined.
