Abstract
A method for producing galvanized metal sheet or strip material having a zinc coating on one side only. The method includes utilizing the strip as a bipolar electrode and electrolytically removing a zinc coating from one side of the strip while simultaneously depositing a substantially equivalent amount of zinc on the opposite side of the strip. The method is most economically performed with a steel strip having a differential coating of zinc.
