ABSTRACT:
A metal unitary structural member for structural support. The member includes a plurality of web portions extending radially from each other and extending with each other in an axial direction, and a plurality of outer portions extending in an axial direction with the web portions and between the web portions in cross-section. The plurality of outer portions defines an outer surface of the member. The web portions may extend from a substantially central portion. The plurality of web portions may include perforations.
