Why does galvanized coil plate need surface polishing?

1. Improve the surface smoothness of the galvanized sheet. After casting and rolling, the flatness of the galvanized sheet is improved to a certain extent. The corrugation of the galvanized sheet is partially removed, and the slag particles or other uneven spots on the surface can be reduced. Okay, make the surface smoother and smoother. 2. Adjust the roughness of the galvanized sheet. By controlling the roughness of the roller surface during the operation of the precision extruder, the original uneven roughness of the galvanized sheet surface can be unified into a certain range. In this way, the coating properties of the product and the wettability during the production process can be improved. 3. Improve the surface color of galvanized sheet rolls. For products with small or no zinc flakes, galvanized sheets can be polished to obtain a smoother and more uniform surface. For some private enterprises, the use of large zinc flower products as color-coated plates can make the zinc flower protrusions formed by large zinc flower crystals smooth and even, making the zinc flower become blurred, which is beneficial to covering the zinc flower during coating.

4. Improve the processing characteristics of galvanized steel sheets. Through deep processing, the compromise platform of galvanized steel sheets can disappear or become insignificant, and the metal load lines caused by subsequent processing can be avoided.
