What is the difference between Cold and Hot-dip galvanized welded wire mesh?

Hot-dip galvanized welded wire mesh is to galvanize the welded wire mesh in the case of heating. After melting the zinc into a liquid state, the welded wire mesh is immersed therein, so that the zinc will form an interpenetration with the base material, and the bonding is very tight.

Other impurities or defects are not easily left in the middle, similar to the melting of the two materials in the plating part, and the thickness of the coating is large, can reach 100 microns, so the corrosion resistance is high, the salt spray test is no problem for 96h, which is equivalent to the normal environment. 10 years to 15 years.

However, for the Cold galvanized welded wire mesh, the welded wire mesh is electroplated at a normal temperature. Although the thickness of the plating layer can also be controlled to 10 mm, the bonding strength and thickness of the plating layer are relatively low, so the corrosion resistance is worse than On the Hot-dip galvanized welded wire mesh.
