ABSTRACT OF THE DISCLOSURE Steel strip is first heated to a predetermined temperature suitable for imparting desired properties to the strip and is then immersed in an aqueous bath maintained at substantially its boiling temperature. The composition of the aqueous bath is preferably adjusted to ensure the formation of an oxide film on the entire surface of the strip. After the strip has been withdrawn from the bath, oxide is eliminated from at least part of the surface of the strip, e.g. from one or both faces, by removal of the oxide or by reduction of the oxide. Simultaneously or subsequently, the strip is heated to a given temperature, e.g. 420-550°C, maintained at this temperature, and immersed at this temperature in molten zinc.
