PURPOSE: To provide a member for structure, which has large mechanical strength and by which the area of a specific surface extending in the longitudinal direction, can be made large compared with a cross-sectional area in the longitudinal direction of an intermediate height though a cross-sectional area in a plane orthogonally crossing a longitudinal direction is comparatively small. CONSTITUTION: In a member for structure, which is a straight bar made of stainless steel, the cold rolling of a bar material made of a stainless steel is performed under conditions that a draft in the center part is set to 10 to 60%, a draft at the end parts is set between 0% and 10%, and further so that a part from the center part to the respective tip parts is enlarged at a gradient of an angleαof 20 to 90 deg. to form the bar made of stainless steel. |
