ABSTRACT:
In a method for electroplating a steel strip with a coating metal, in particular, zinc or a zinc-containing alloy, a thin protective layer consisting of the coating metal is temporarily electrodeposited on one side of the steel strip. After complete coating of the other side, this protective layer is completely or essentially removed in a stripping step in which the coated steel strip as the anode is moved through a stripping electrolyte. The stripping electrolyte contains a sequestering agent, advantageously sodium gluconate.
