Galvanized electric welding net is the current use of large galvanized wire drawing products, galvanized electric welding net is divided into cold galvanized electric welding net and hot galvanized electric welding net. The price of cold galvanized welding net is cheaper than that of hot galvanized welding net, and the corrosion resistance is worse. Production process standard of cold galvanized electric welding mesh. Q195 low carbon metal wire is used for the selection of galvanized electric welding mesh, and the wire rod is drawn by wire drawing machine.
The diameter after wire drawing is generally 0.3mm – 3mm, the wire after wire drawing is not very strong, it needs to be annealed, annealing this step is very important, can ensure the production of galvanized welding mesh, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its anti-corrosion performance is poor and its service life is short, so it needs to be galvanized or dipped.
The prepared black wire welding net is placed in the environmentally friendly galvanizing equipment for galvanizing treatment, and the galvanized galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. However, whether the tensile force of an electric welding mesh is qualified can only be tested by professional tools.
The exposed sides of the galvanized welding net can not exceed 2mm, so that it is qualified. And in the welding mesh of each warp and weft wire crossing place, must be welded very firmly, and if you want to weld very firmly, both sides must have some warp and weft wire out, and the length must be controlled within two millimeters. From the mesh distribution is not uniform, galvanized is not uniform, but also to see whether the welding mesh is qualified standards.
There are many categories of large rolls of galvanized wire, and different categories can be applied to different scenarios. The common application of galvanized iron wire is the application of the construction industry, one is the use of binding wire, whether it is the binding of scaffolding or reinforcement, all need galvanized iron wire to carry out, the common specifications are 22 and 24 wire, the common length is 30cm, 35cm, 40cm, 45cm, 50cm. There is also a 20kg or 50kg bundle of No. 18, 16, 14, 12, 10 galvanized coil wire.
