The present invention relates to a frame applied to a structure such as a steel house. The frame for a steel house according to the present invention includes: first to six plate units divided to have predetermined widths by being vertically bent by first to four bent lines extended in one direction to be parallel to each other; expansion bent units formed by expanding and bending one side of the third plate unit and one side of the fourth plate unit to the outside; and expansion plate units of which a cross section is formed at a width wider than a distance between the third and fourth plate units by the expansion bent units. The frame for a steel house is characterized by increasing a cross sectional area and a section modulus for the fit-up of finishing materials. Accordingly, the present invention is capable of increasing the cross sectional area and the section modulus by forming the bent portions on the frame member, thereby facilitating the fit-up of interior and exterior finishing materials and providing an effect of increasing the fixation strength and loading strength of the finishing materials. |
