Skinpass is a light rolling process applied to the surface of steel sheets after coating to improve mechanical properties and surface appearance. This process uses rollers with controlled rolling force to slightly compress the surface of the steel, enhancing its hardness, brightness, and the adhesion of the coating layer.
2. Advantages
- Increase Hardness and Durability: Helps the steel withstand mechanical impacts during processing and usage. - Improve Surface: Enhances brightness and uniformity, facilitating the subsequent coating process. - Reduce Slippage: Increases surface friction, aiding in smooth processing during subsequent operations.
3. Applications
Skinpass is applied after the galvanizing or alloy coating process to enhance both the surface quality and mechanical properties of the steel. This process is especially critical in the production of color-coated steel, where high adhesion and aesthetics of the coating are required.
4. Technical Specifications
- Rolling Force: Up to 600 tons. - Steel Thickness After Rolling: Depends on product requirements and line settings. Accurate control of the rolling force and thickness ensures the desired surface quality and mechanical properties for the final product.
5. Quality Standards
Products processed by Skinpass typically meet international standards such as JIS G3302, JIS G3323, and ASTM A653/A653M.
