What is the reason for the generally high price of galvanized welded wire mesh?

When it comes to hot-dip galvanized welded wire mesh, many people's first reaction is that it is no different from cold-galvanized welded wire mesh. The answer is that the two are indeed not the same. Galvanized welded wire mesh is cold galvanized welded wire mesh and hot-dip galvanized welded wire mesh. Compared with cold galvanized welded wire mesh, the price of hot dip 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-dip galvanized welded wire mesh higher than that of cold-galvanized welded wire mesh? The processing technology of hot-dip galvanized welded wire mesh is disordered, and its corrosion resistance is much stronger than that of cold-dip galvanized welded wire mesh. Galvanizing refers to adding a layer of zinc element to the welding mesh. We all know that zinc is more stable than iron, so zinc is not easily oxidized in the air. By galvanizing the welded wire mesh, the corrosion resistance of the hot-dip galvanized welded wire mesh is greatly improved.
As we all know, before galvanizing, the welded mesh needs to remove the rust on the welded mesh and then galvanize. The cold galvanized welded wire mesh is a layer of zinc layer formed on the welded wire mesh after rust removal using the DC principle. The hot-dip galvanized layer is thicker than the cold-galvanized layer, and the process is more disordered than the cold-galvanized welded wire mesh.
In the process of hot-dip galvanizing, high-temperature molten zinc blocks are selected to form zinc liquid. It has high requirements on temperature, and the temperature of the zinc liquid must be controlled, neither high nor low. The zinc solution has slow activity at high temperature and high zinc content. As a result, the zinc layer on the welded wire is too thick and uneven, and even forms a zinc block, which affects the beauty of the welded network; if the temperature is too high, it will damage the appearance of the hot-dip galvanized welded wire mesh. The uneven color makes up for the color difference of the welded wire mesh, which affects the beauty of the welded wire mesh. Of course, the corrosion resistance of hot-dip galvanized welded wire mesh is also stronger than that of cold-dip galvanized welded wire mesh, and the price will be higher.
