摘要： A method of producing highly corrosion-resistant surface-treated steel plates where Cr elusion is small in spite of drying at low temperatures and corrosion resistance is excellent. In a process for producing surface treated steels where Zn type plated steels are treated through (i) chromate treatment, (ii) coating a resin composition and (iii) baking treatment, zirconium fluoride ion and Zn ion of appropriate amounts are added into the chromate bath, and Cr.sup.6+ /Cr.sup.3+ ratio in the bath is controlled to be low. Further the resin composition to be coated after the chromate treatment is rendered a solvent type resin composition obtained by adding silica and/or sparingly water soluble Cr compound to basic epoxy resin.
