In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.

Dip is one of the anticorrosion methods of galvanized diamond net. For hook mesh immersion is one of the methods of anti-corrosion, now the domestic more mature method is: powder immersion method, it originated from the fluidized bed method, the so-called fluidized bed is used in the Winkler gas furnace on the oil contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in metal coating. So sometimes it is still called “fluidized bed coating method”, the actual process is to add the powder coating to the bottom of the porous, breathable container, the blower from the bottom into the treated compressed air, so that the powder coating turned to the “fluidization state”. It becomes a fine, evenly distributed powder.

Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.
