The protective duration of the galvanized layer of large roll galvanized wire is closely related to the thickness of the coating. Generally speaking, in relatively dry main gas and indoor use, and in harsh environmental conditions, the thickness of galvanized layer needs to be very high. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance.

Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
