Abstract
A product is produced from a rolled strip material with the steps: providing a substrate in form of a strip material from sheet steel, rolling of the substrate in form of strip material, electrolytic coating of the substrate with a first metal coating material, wherein the electrolytic coating is carried out after the rolling, applying of a second coating material as a scaling protection coating on the substrate coated with the first coating material, and hot-forming of the substrate, wherein the hot-forming is carried out after the application of the second coating material.

A method for producing a product from a rolled strip material, comprising:
- providing a substrate in form of a strip material from sheet steel;
- rolling the substrate to produce a rolled strip material;
- performing an electrolytic coating of the substrate with a first metal coating material, wherein the electrolytic coating is carried out after the rolling;
- applying a second coating material as a scaling protection coating on the substrate coated with the first coating material;
- and
- hot-forming of the substrate, wherein the hot-forming is carried out after applying the second coating material;
- wherein the second coating material is a compound with metallic components, wherein the composition of the second coating material is selected such that the metallic components include predominantly elements which are more ignoble than the sheet steel of the substrate, thereby providing a cathodic corrosion protection.
A product from a rolled strip material made of sheet steel with a coating from a first coating material and a second coating material, produced according to the steps of:
- providing a substrate in form of a strip material from sheet steel;
- rolling the substrate to produce a rolled strip material;
- performing an electrolytic coating of the substrate with a first metal coating material, wherein the electrolytic coating is carried out after the rolling;
- applying a second coating material as a scaling protection coating on the substrate coated with the first coating material;
- and
- hot-forming of the substrate, wherein the hot-forming is carried out after applying the second coating material;
- wherein the second coating material is a compound with metallic components, wherein the composition of the second coating material is selected such that the metallic components include predominantly elements which are more ignoble than the sheet steel of the substrate, thereby providing a cathodic corrosion protection.
