ABSTRACT OF THE DISCLOSURE Coated steel sheets are provided in which the coating provides corrosion resistance and is of substantially uniform thickness, the coating is formed by dipping the steel sheet into a suspension comprising at least one substance selected from the group consisting of a water soluble organic polymer resin, a water-dispersible organic polymer resin and a water-dispersible sol of a metal compound, together with an infusible powder of a water-insoluble polymer resin, removing the coated steel sheet from the suspension and curing the coated composite by heat treatment. In certain cases, a metal powder, a metal alloy powder or a powder of a difficultly water-soluble or water-insoluble metal compound may be included in the suspension to improve the corrosion resis- tance.
