Abstract
Producing one-side zinc electroplated strip having enhanced phosphating characteristics. Prior to electroplating, the non-electroplated side of the steel strip is cathodically pickled. Cathodic pickling minimizes staining and etching to the non-electroplated strip surface by the zinc electrolyte during electroplating of the opposite strip surface.
