<p>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 resistance.</p> |
