A cast strip for an H-shape steel having excellent fire resistance and toughness for use as a structural member for constructions and a shape steel having a flange, such as an I-shape steel, produced by accelerated cooling and controlled rolling of the cast slab, are produced in an in-line manner. After the regulation of the oxygen concentration of a molten steel by a predeoxidation treatment in a steel making process to form a steel having predetermined ingredients, the steel is subjected to final deoxidation with a minor amount of Al to provide a cast slab containing, in a dispersed state, compound oxide precipitate having a capability of forming intragranular ferrite. The stead is then subjected to a treatment comprising a combination of water cooling between rolling passes with accelerated cooling after hot rolling to attain refinement of the structure and a low alloy steel, thereby improving the strength at room temperature and at high temperature and the toughness.
