Sheet steel having a deterministic surface structure

A steel sheet skin-pass rolled with a deterministic surface structure, wherein the surface structure is impressed into the steel sheet starting from a surface of the steel sheet, wherein the surface structure comprises a flank region that runs from the surface to a trough region, wherein the flank region has a roughness Ra of greater than 20 nm to less than 300 nm, wherein the steel sheet further comprises a zinc-based coat which is applied by electrolytic coating, wherein the steel sheet is additionally provided with a process medium with an applied amount of up to 2 g/m2.
