Four major functions of galvanized coil surface finishing

1. Improve the surface straightness of galvanized sheets. After finishing, the straightness of the galvanized sheet must be improved, and the corrugation of the galvanized sheet can be partially removed. At the same time, the slag particles or other uneven spots on the surface can also be smoothed to make the surface appear fine and smooth. 2. Adjust the surface roughness of the galvanized sheet surface. By controlling the smoothness of the surface of the work roll of the finishing machine, the original uneven roughness on the surface of the galvanized sheet can be reduced to a certain range. This improves the paintability and wettability of the product during processing. 1. Improve the surface straightness of galvanized sheets.

For zinc flower and zinc flower-free products, the galvanized sheet can obtain a surface with a more uniform glossiness according to the finishing ability. For some private enterprises that use large zinc flower products as color-coated boards, the zinc flower bumps and different roughnesses formed by the large zinc flower crystals can be smoothed and consistent, making the zinc flower look blurry, which is conducive to Cover up the splatter when spraying.

4. Improve the processing characteristics of galvanized sheets. Through smoothing, the compromise site of the galvanized steel sheet can be reduced or not obvious, which can prevent metal slip lines from being formed in subsequent extrusion molding.
