Abstract

A surface-coated steel sheet of stainless steel is disclosed and has a coating which is made up of at least one metallic corrosion protection layer (1.1) and at least one further layer (1.2) applied to the metallic corrosion protection layer. For such a steel sheet to offer, without a color-imparting organic surface coating, a high-quality impression in terms of aesthetic effect and additionally, have a very high UV resistance, the at least one further layer (1.2) may be a metallic layer or be formed from a metallic layer, where the metallic layer (1.2) is based on nonrusting stainless steel, a chromium- and/or nickel-containing alloy, copper and/or a copper alloy. The at least one further metallic layer (1.2) can optionally be provided with a transparent layer (1.3). Furthermore, a process for producing such a surface-coated steel sheet is described.
