PROBLEM TO BE SOLVED: To provide a steel-frame coating structure which is excellent in constructibility, and which is excellent in its shape retentivity even if it is exposed to a high temperature for a long period of time. SOLUTION: This steel-frame coating structure comprises a steel frame for a building structural material, and a steel-frame coating sheet which consists of 55-85 wt.% inorganic fibers, a 5-30 wt.% thermally-expansible inorganic substance, a 5-25 wt.% inorganic binder, and a 5-15 wt.% organic binder. The steel-frame coating structure is characterized as follows: the inorganic binder, which is contained in the steel-frame coating sheet, is composed of a sinterable inorganic material with a melting point of 650-1,000°C; and the steel-frame coating sheet is provided in such a manner as to cover the steel frame for the building structural material.
