Abstract (en)
[origin: WO2011054571A1] The invention relates to a process for producing A steel strip having a cathodic anti-corrosion coating, wherein the steel strip is hot-rolled and then cold-rolled, wherein the steel strip is subjected to electrolytic galvanizing and, following the electrolytic galvanizing, is heat-treated in a hood-type annealing furnace at temperatures ranging from 250°C to 350°C for a time period of 4 to 48 hours and, as a result, a zinc-iron layer is produced.
