The main difference between the different processes is that there are two types of methods for establishing the base layer and the thickening of the plating layer. In addition to the power supply, mechanical plating does not require regulation of the power supply, nor does it require a heating device. It is easy to operate, simple in equipment, low in energy consumption, and quick in effect.

Compared with electroplating, when the thickness of Galvanized Steel Coil made in China coating is less than 12.5mm, electroplating is slightly superior to mechanical plating, but the difference is not big; as the thickness of the coating increases, the advantage of mechanical plating gradually disappears; when the thickness of the coating reaches 30mm, electroplating and machinery The cost ratio of plating is about 1.8:1. With the development of galvanizing technology and the further improvement of automotive anti-corrosion performance requirements, the application of Galvanized Steel Coil made in China on the vehicle body is more and more extensive, and the application ratio of white body galvanized steel sheets for European and American passenger cars is as high as 90%.

Nowadays, Galvanized Steel Coils made in China have been applied in domestic self-owned brand passenger cars. With the continuous improvement of the quality of passenger car bodies, it is believed that the galvanizing technology on the vehicle body is more mature, thus effectively improving the anti-corrosion performance of the products and optimizing the anti-corrosion design cost.
