A one-piece stud has a central longitudinal side; a first longitudinal side joined at a 90° angle to the first end of the central longitudinal side; and a second longitudinal side joined at a 90° angle to the second end of the central longitudinal side. The central side has a first and a second planar surface joined by an acute isosceles triangular channel midway between. The first longitudinal side is formed of a third and a fourth planar surface joined by an acute isosceles triangular channel midway between. The second longitudinal side has a fifth and a sixth planar surface joined by an acute isosceles triangular channel midway between. At an end opposite the 90° joint, the first longitudinal side and the second longitudinal side have free ends each forming a gapped right isosceles triangle. The longitudinal channels increase the axial capacity and the moment capacity of the stud.
