A weldable paint-coated steel sheet having improved corrosion resistance, weldability and workability, comprising a zinc alloy coated steel substrate and a paint coating applied thereon, said paint coating containing zinc alloy powder and at least one of the groups consisting of zinc powder and hard electric conductive powder.

In a continuous electrolytic processing apparatus for a metal strip, a variation in electrode distance is achieved by an electrode-holder positioning means 40 which comprises expansible tubes 6 elastically holding the electrode holder 7. A fluid medium is admitted into the expansible tubes 6 at an adjustable pressure or amount. The electrode distance can be adjusted to conform with the processing conditions at a value which allows very efficient processing.

A method for electroplating a metal strip to be plated includes continuously running the metal strip through the interior of a plating vessel of a cylindrical form having a rectangular cross section, the upper and lower walls of such vessel being constructed of an insoluble anode material which is to function as an anode, and compulsively circulating a plating solution in a direction counter to the running direction of the metal strip within the plating vessel and an apparatus for carrying out the same, whereby a high speed plating is performed and the replacement of the anodes can be minimized.
