Effect of Surface Finishing of Galvanized Steel Sheet
After China Wave Type Galvanized Corrugated Steel Sheet is finished, it has a great effect on surface quality improvement and performance improvement. There are mainly the following aspects:
1. Improve the surface flatness of the galvanized sheet. After finishing, the flatness of the galvanized sheet is improved, the wave shape of the galvanized sheet is partially eliminated, and the slag particles or other uneven spots on the surface can be flattened to make the surface of the galvanized steel sheet become Smooth and flat.
2. Adjust the roughness of the surface of Wave Type Galvanized Corrugated Steel Sheet. By controlling the roughness of the surface of the work rolls of the finishing machine, the uneven roughness of the surface of the galvanized steel sheet can be unified to a certain range. This improves the paintability of the product and the lubricity during processing.
3. Improve the surface color of the Galvanized Corrugated Steel Sheet. For small zinc flower and zinc-free flower products, the galvanized sheet can be made to have a more uniform surface with a uniform gloss. For some private enterprises, the use of large zinc flower products as color-coated substrates can make the zinc flower bumps and different glosses formed by the large zinc flower crystals smooth and uniform, which makes the zinc flowers blurred and unfavorable. Cover the zinc flower when painting.
4. Improve the processing performance of Wave Type Galvanized Corrugated Steel Sheet. By finishing, the yielding platform of the galvanized steel sheet can be eliminated or become inconspicuous, and the metal slip line can be prevented from being generated in the subsequent processing.
