  • Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.

  • Similar to two materials in the coating part melting together, and coating thickness can reach 100 microns, so high corrosion resistance, salt spray test 96h no problem, equivalent to 10 years under the usual environment; Cold galvanizing is electroplating at room temperature. Although the thickness of the coating can also be controlled, the binding strength and thickness of the coating are relatively low, so the corrosion resistance is poor.

  • Annealed wire is a kind of soft iron wire made of low carbon steel by cold drawing, heating, constant temperature and heat preservation. The composition of the wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into 6.5mm thick steel bar, that is, the wire rod, and then it is put into the wire drawing device to draw the wire of different diameter, and gradually reduce the aperture of the drawing disk, cooling, annealing, plating and other processing technology to make a variety of different specifications of the wire.
