Abstract
In a process for the electrolytic zinc coating of high-grade steel on one and two sides, the latter is connected as a cathode in the form of a high-grade steel strip in a galvanic cell, and metallic zinc is deposited on the high-grade steel strip from an aqueous solution of a zinc salt with a pH value of 1.0 to 2.5, preferably 1.5 to 2.0, as a result of which a contact corrosion with zinc-coated metal sheet is avoided, which is particularly important in the motor-car industry.
