Abstract
The present disclosure relates to a process for producing a surface-treated and surface-finished sheet steel. A sheet steel having a zinc-based coating is provided, wherein zinc grains are distributed within the coating. The surface-treated sheet steel are skin-pass rolled to form embossed regions and unembossed regions on the surface of the sheet steel provided with a zinc-based coating. Skin-pass rolling is performed with a degree of skin-pass greater than 1% in such a way that due to the force exerted by the skin-pass rolling the zinc grains in the embossed region are altered in dimension relative to the zinc grains in the unembossed region.
