ABSTRACT:
A steel sheet with its surface prepared for paint coating is disclosed. The surface treated steel sheet comprises a base sheet, and an iron-zinc alloy film plated on the base sheet in an amount of at least 0.1 g/m.sup.2 and having an iron content of from 3 to 30%. A composite silicate resin film is coated on the iron-zinc alloy film in an amount of from 0.05 to 5.0 g/m.sup.2. The resin film is composed of an acrylic copolymer, an epoxy resin, a silica sol and a trialkoxysilane compound. The treated surface provides superior paintability, degrease resistance and corrosion resistance after pain coating.
