  • Cold galvanized by electrolytic action to metal and other materials surface attached to a layer of metal film, so that the surface of the material uniform texture, anti-corrosion wear, appearance is more beautiful. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other “rough” workpiece long-term rust prevention.

  • 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.

  • Stainless steel barbed rope according to the different categories of nickel applications are not the same, in the dry indoor environment using 304 stainless steel effect is quite good. However, in both rural and urban areas, to maintain its appearance outdoors, it is necessary to stop washing frequently. In heavily polluted industrial areas and coastal areas, the surface will be so dirty that it will rust. But to achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is commonly used for curtain wall, side wall, roof and other building uses, but in the corrosive industrial or Marine atmosphere, it is best to use 316 stainless steel.

  • Large coil galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire. Galvanized wire in the process of smelting there are a lot of need to pay more attention to the place, galvanized wire products in the manufacturing process will experience a lot of process, of which the following galvanized wire annealing is a very important step, this step to the nature of galvanized wire has brought a lot of help.
