Galvanized welded wire mesh is electroplated under heating conditions. Zinc melt into liquid, the base metal into among them, the zinc and the base metal to form mutual penetration, tightly bonding, the middle is not easy to residual impurities or other defects, like two materials in coatings and zone melting together, coating thickness can reach 100 microns, high corrosion resistance, therefore, there is no question of 96 hours salt spray test, the equivalent of normally environment in 10 years.
While cold galvanizing is electroplated at room temperature, this process is not mentioned, although the thickness of the coating can also be controlled, but the bonding strength and thickness of the coating is relatively low, so the corrosion resistance is poor. Galvanized wire welding production process details is the first black wire welding after the completion of the surface galvanized treatment.
Galvanized welding mesh surface galvanized is divided into two kinds; One is hot dip galvanizing (high zinc content, strong corrosion resistance, life of about 7 years), the other is cold dip galvanizing general export will be used (low zinc content), no solder joints, relatively long life than ordinary. Galvanized welding mesh welding technology is black wire welded into a large coil of black wire welding mesh – black wire welding mesh for hot dip galvanized anticorrosive treatment – coil into a small coil – packaging to make hot dip galvanized complete.
