When it comes to hot-dip galvanized welded wire netting, many people's first reaction is that it is no different from cold-plated welded wire netting. The answer is that the two are indeed different. The galvanized welded wire mesh includes cold galvanized welded wire mesh and hot galvanized welded wire mesh. Compared to cold galvanized welded wire mesh, the price of hot galvanized welded wire mesh will be higher than that of cold galvanized welded wire mesh.
Perhaps many customers will have the same question, why is the price of hot galvanized welded wire mesh higher than that of cold galvanized welded wire mesh? The processing technology of hot galvanized welded wire mesh is disordered, and its corrosion resistance is greatly stronger than that of cold galvanized welded wire mesh. Galvanizing refers to adding a layer of zinc to the welding mesh. As we all know, zinc is more stable than iron, so zinc is not easily oxidized in air. The corrosion resistance of the hot-dip galvanized welded wire mesh is greatly improved by galvanizing the welded wire mesh.
It is well known that before galvanizing, the welding net needs to remove the rust on the welding net before galvanizing. The cold galvanized welding net is a zinc layer formed on the welding net after rust removal using the DC principle. The hot galvanized layer is thicker than the cold galvanized layer, and the process is more chaotic than the cold galvanized welded wire mesh.
In the process of hot galvanizing, molten zinc blocks at high temperatures are selected to form the zinc liquid. "Its requirements for temperature are very high, and it is necessary to control the temperature of the zinc liquid well, neither high nor low.". The activity of zinc liquid at high temperature is slow and the zinc content is high. Thereby causing the zinc layer on the welding network to be too thick and uneven, even forming zinc blocks, affecting the beauty of the welding network; Too high a temperature can damage and color the appearance of the hot-dip galvanized welded wire mesh. Uneven colors compensate for the color difference of the welded mesh, affecting the beauty of the welded mesh. Of course, the corrosion resistance of hot galvanized welded wire mesh is also stronger than that of cold galvanized welded wire mesh, and the price will be higher.
