Zusammenfassung:	A steel product may include a metallic anticorrosion coating of an aluminum alloy. So that such a steel product possesses high media resistance, more particularly high acid resistance and corrosion resistance, the steel product may be immersed in a liquid-melt coating bath that includes an aluminum alloy. In addition to Aluminum and unavoidable impurities, the aluminum alloy may include at least one of 0.2-2% by weight Mn or 0.2-7% by weight Mg, 0.5-5% by weight Fe, and at least one of 0.05-0.4% by weight Ti or 0.05-0.4% by weight Zr. A method for producing such steel products may involve providing a steel product in a hot-rolled or cold-rolled state, activating a surface of the steel product to remove passive oxides, and coating the surface-activated steel product by immersion in a liquid-melt coating bath that comprises an aluminum alloy having the aforementioned composition.
