Abstract
A method of producing both-side electrolytically zinc plated steel strips utilizing a chloride bath including the steps of plating one side of the steel strip in a first plating cell, wetting the thus one-side plated steel strip in a wetting tank, and then plating the other nonplated side of the steel strip in a second plating cell. The method provides for limiting the concentration of zinc in the wetting solution to a range of 0.1-50 g/l so as to improve the zinc coating coverage, glossiness and corrosion resistance.
