Perfect surface treatment for hot and cold-rolled strip

Cold-rolled strip can be found almost everywhere today. The surface effects of cold-rolled strip vary: glossy, matte, or everything in between, each of which is beautiful. However, the strip surface must not only be aesthetically pleasing, but also have important technical functions. For example, the correct roughness ensures a perfect paint surface. Other material properties are also crucial for further processing, such as deep drawing operations.

One of the most important steps is the skin-passing process of cold-rolled strip. The skin-passing mills (SPM) of Sinoventos achieve the exact mechanical properties and geometrical dimensional requirements required. Skin-passing achieves the correct yield point and the required surface characteristics (such as roughness and flatness).
