A steel sheet for making cans carrying a layer of a thermoplastic resin having a thickness of 3 to 100 microns on at least one surface thereof which, when shaped into a can, will define its inner surface, and a foil of aluminum or an aluminum alloy having a thickness of 5 to 100 microns on the resin layer. Also disclosed is a can for holding a drink which is formed from such a steel sheet, and which has a layer of a thermosetting resin on the foil. A method of making any such can is also disclosed.

A hydrated chromium oxide-coated steel strip which has a satisfactory weldability and resistance to corrosion under a lacquer coating and which is useful for producing welded cans and other containers, comprises a steel strip substrate, plated nickel base layers formed on the surfaces of the steel strip substrate and having a weight of 150-2500 mg per m.sup.2 of each surface of the substrate, hydrated chromium oxide-containing coating layers formed on the surfaces of the plated nickel base layers and having a weight of 2-20 mg, in terms of metallic chromium, per m.sup.2 of each surface of the substrate, and, optionally, plated tin intermediate layers formed between the plated nickel base layers and the chromate-containing coating layers and having a weight of 100-2000 mg per m.sup.2 of each surface of the substrate, the hydrated chromium oxide-containing coating layer optionally being composed of a metallic chromium underlayer in a weight of 10 mg or less per m.sup.2 of each surface of the steel strip substrate and a hydrated chromium oxide upper layer, the sum of the weights of the underlayer and the upper layer being 2-20 mg, in terms of metallic chromium, per m.sup.2 of each surface of the steel strip substrate.
