1. Pickling
Pickling is a common process for surface treatment of cold-rolled plates. Its purpose is to remove scale, rust and contaminants on the surface of cold-rolled plates and improve the surface finish and flatness. Pickling generally uses hydrochloric acid as the pickling solution. The cold-rolled plates are soaked in the pickling solution to cause a chemical reaction with surface contaminants to remove the contaminants. The surface quality of cold-rolled plates after pickling is significantly improved.
2. Oil
In order to reduce some problems that may arise from secondary oxidation, oiling will also be used appropriately. Common oiling methods include roller coating and spraying. The oiling agent is evenly applied on the surface of the cold-rolled plate to make the oil film more uniform. The surface quality of the cold-rolled steel.

The oiling agent is evenly applied on the surface of the cold-rolled plate to make the oil film more uniform. The surface quality of the cold-rolled plate after oiling is further improved, but it is not permanent. The same oiling also requires regular replenishment and maintenance.
3. Galvanized
Galvanizing is a surface treatment method. By plating a layer of zinc on the surface of cold-rolled plates, a coating that can properly help resist corrosion is formed on the surface. The surface quality of cold-rolled plates can be improved and the corrosion resistance can be enhanced. However, the thickness and durability of the galvanized layer have certain limits, so it is still necessary to choose the appropriate galvanizing method according to the specific application scenario.
4. Spray
Spraying is a surface treatment method that evenly applies paint to the surface of cold-rolled plates to form a protective layer. During the application process, both manual and mechanical spraying functions can be used. The difference between the two is the amount used and the size. The surface quality of the sprayed cold-rolled plate is further improved and the corrosion resistance is enhanced, but the service life of the coating is limited and requires regular inspection and maintenance.
