Abstract: The present disclosure relates to a hot-dip-coated steel sheet having a Zn—Mg—Al coating which includes aluminum at between 0.1 and 8.0 wt %, magnesium at between 0.1 and 8.0 wt %, the balance being zinc and unavoidable impurities, wherein the coating comprises zinc grains and further phases of magnesium and/or aluminum and also eutectic structures including at least intermetallic zinc-magnesium phases, wherein a native oxide layer is formed on the coating. In accordance with the present disclosure, the coating beneath the native oxide layer has an area fraction of at least 35% in which there is an average nanohardness of at least 4 GPa.

Abstract: The invention relates to a sheet steel (1) coated with a zinc-based coating and skin-pass rolled with a deterministic surface structure (2), and to a method for producing it.

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.

Abstract: The invention relates to a sheet metal having a deterministic surface structure, the surface structure being impressed into the sheet metal, the surface structure having at least one peak region and at least one valley region, the peak region and the valley region being joined by a flank region. The invention further relates to a method for producing a formed and coated sheet-metal component.

Abstract: The invention relates to sheet steel, more particularly a coated sheet steel, which is skin-pass rolled with a deterministic surface structure, and to a method for producing this steel.
