  • (8) galvanized wire coated hexagonal mesh is coated with a layer of PVC protective layer on the surface of galvanized iron wire, and then woven into a variety of specifications of hexagonal mesh. This layer of PVC protective layer will greatly increase the service life of the net, and through the choice of different colors, so that it can be integrated with the surrounding natural environment.

  • Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.
