Now most people buy barbed rope choose blade barbed rope, why is this? From the material blade barbed wire technology blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out sharp knife sheet, high tension galvanized steel wire or blade barbed wire stainless steel wire as core wire combination of the resistance device. Because the gill net shape is not easy to contact, so it can achieve excellent protective barrier effect. The primary raw materials of products are galvanized sheet and stainless steel plate.

If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

Large roll galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Large roll galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics.
