Abstract
A method for coating a hot-rolled or cold-rolled steel flat product, containing 6-30% wt. Mn, with a metallic protective layer by hot-clip coating in a melt bath. The coating, achieved with increased production reliability, is optimised by the steel flat product being subjected to a pickling treatment in which the manganese oxide adhering to the steel flat product is essentially fully removed in the pickling bath before the steel flat product enters the melt bath.
