Procedure

A method of preparing a steel surface for painting or enamelling which comprises the step of coating the surface with a tin-zinc alloy by electrodeposition from an aqueous electrolyte containing zinc sulphamate, tin sulphate and sulphamic acid, the proportion of tin sulphate to zinc sulphate being such as to provide a weight ratio of not less than 20:80 and not more than 60:40 between the tin and the zinc present in the solution.
