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.
Claims37
A metal unitary structural member, comprising:
- an elongated, axially extending central portion;
- a plurality of web portions extending radially from said central portion and extending in an axial direction along a length of said central portion;
- and
- a plurality of outer portions extending in said axial direction along a length of said central portion and between said web portions in cross-section, said plurality of outer portions defining an outer surface of the member;
- wherein said plurality of web portions each include a plurality of perforations.
A metal unitary structural member comprising:
- a plurality of perforated 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 said web portions and extending between said web portions in cross-section, said plurality of outer portions defining a radially outer surface of the member.
A metal unitary structural member comprising:
- an elongated, axially extending central portion;
