Embodiment Construction
[0021] Systems for surface coating of steel sheets consisting of carbon steel (C-section steel) are available at figure 1 shown in . This plate-like product 1 consisting of a C-section steel to be coated according to the invention has, for example, the following chemical composition:
[0022]
[0023]
[0024] Carbon steel is preferably supplied to steel mills as the steel ring 2 . The thickness of the strip-shaped C-shaped steel 1 is, for example, in the range of 0.05 mm to 30 mm. The strip-shaped C-shaped steel sheet 1 is subjected to a first surface coating after hot and / or cold rolling 3, which is used for corrosion protection on the wide side and, depending on the coating system, also for the edges of the steel strip 1 . The surface coating or zinc coating can be e.g. fire galvanized (Z), electrolytic zinc coating (ZE), zinc-aluminum coating (ZA), aluminum zinc coating (AZ), fire aluminum coating (FAL) Or zinc magnesium coating (ZM).
[0025] The steel strip 1 ...

Abstract
The invention relates to a surface-finished steel sheet made of carbon steel with a coating that is formed from at least one metallic corrosion protection layer (1.1) and at least one additional layer (1.2) applied with a material bond to the metallic corrosion protection layer. In order for such a steel sheet to do without organic colour-providing paint-coating, to convey a high-quality aesthetic impression and also to have a very high UV resistance, according to the invention the at least one additional layer (1.2) is a metallic layer or is formed from a metallic layer, wherein the metallic layer (1.2) is based on stainless steel, a chromium-containing and / or nickel-containing alloy, copper and / or a copper alloy. The at least one additional metallic layer (1.2) can optionally be provided with a transparent layer (1.3). A method for producing such a surface-finished steel sheet is also described and claimed.
Description
technical field [0001] The invention relates to a surface-coated steel sheet consisting of carbon steel and having a coating consisting of at least one metallic corrosion protection layer and at least one additional layer applied with a material bonded to the metallic corrosion protection layer. The invention further relates to a process for the production of surface-coated steel sheets, wherein at least one metallic anti-corrosion layer is applied with a material bonded to a plate-shaped product consisting of carbon steel and at least one additional layer is applied with a material bonded to at least one The material of the metal anti-corrosion layer. Background technique [0002] Due to poor corrosion resistance, uncoated carbon steel is usually coated with zinc to prevent corrosion. For aesthetic reasons, usually a multi-layer, pigmented organic surface coating is subsequently applied and this further increases the corrosion resistance. However, chemicals are present in...
