After the welding mesh is welded by the welding machine, it is generally a large roll of electric welding mesh, and each roll of electric welding mesh has 100-200 meters. In the process of galvanizing need to be intercepted, intercepted to meet the specifications of the welding net, the general length of the welding net is 12 meters, 15 meters, 18 meters, 20 meters, 30 meters, etc. In the hot galvanizing process, the zinc is melted in the high temperature furnace, and then the welding net is put into the furnace, at this time the temperature in the furnace can not be high or low, otherwise the amount of zinc on the welding net is not uniform, resulting in a decline in corrosion resistance, so the temperature control in the galvanizing process is very important. Before the welding mesh enters the zinc furnace, the surface should be flat and there should be no magazines and rusty places. If there is rust, it is necessary to clean the welding mesh, and the welding mesh after cleaning does not have any magazines, and the surface will be very flat after galvanized.
Hot-dip galvanized welding mesh has high corrosion resistance, and there will be no problems when tested for 100 hours under hydrochloric acid mist conditions, which is equivalent to 10 years under outdoor conditions. The service life of hot-dip galvanized welding mesh is reliable.
