Claims
- 1. In a method of producing a both-side electrolytically zinc plated steel strip utilizing a chloride plating bath, the method including the steps of electrolytically 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 electrolytically plating the other non-plated side of the steel strip in a second plating cell, the improvement which comprises wetting the one-side plated steel strip in a chloride wetting solution having a concentration of zinc in a range of 0.1 to 50 g/l, so as to produce the both-side electro-galvanized steel strip having improved zinc coating coverage, glossiness and corrosion resistance and utilizes a chloride bath in the first and second plating cells which comprises 150-300 g/l of zinc chloride.
