gi weldmesh

Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.

A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
