  • Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.

  • 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.
