Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used now is hot galvanizing. However, hot dip galvanizing industry has been developed with the rapid development of cold strip rolling in the past 30 years. The production process of hot-galvanized sheet mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection and so on.

Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire galvanized, is an aspect of maintaining the uniformity of zinc layer.

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

The steel mesh is also called longitudinal reinforcement and transverse reinforcement. The longitudinal reinforcement and transverse reinforcement are spaced at right angles to each other, and all the crossing points are welded together. It has the characteristics of crack – proof, small error and good quality. Steel mesh is mainly used in coal mine roadway, concrete pavement, bridge deck, airport runway and buildings. So, what are the advantages of mesh?
