  • Galvanized iron wire is selected from excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:

  • For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting. In white iron, its carbon and iron together into iron carbide, crack appears white, very strong and brittle quality, for the material of malleable steel. The alloy grade consists of various alloying elements with different compositions and structures.

  • Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.

  • Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

  • Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
