galv wire mesh

Welding net is generally used in construction, breeding chicken and pigeon rabbit cage, balcony protection, machine cover, flower guardrail and so on. According to the welding aperture, wire diameter is different, the use of welding net products are different, such as: the use of insulation wall welding net on housing construction, agricultural circle corn mesh welding net, the use of breeding chicken, mink and other breeding welding net. So what should be paid attention to when choosing the welding net? Mainly in the following three aspects

1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
