Which term describes a hollow structural member used in steel construction?

• A. Hollow Structural Section
• B. Cold-formed Section
• C. Web Plate
• D. Flange Plate

Answer: (A)

Hollow Structural Section describes hollow, load-bearing steel shapes used in framing. This term specifically identifies tubes with square, rectangular, or circular cross-sections that are designed to carry structural loads, often serving as beams, columns, or bracing. The hollow form gives torsional stiffness and a clean aesthetic, making it the go-to description for hollow members in steel construction. Cold-formed Section is a broader category about how shapes are manufactured (formed at room temperature) and includes many shapes, not all of which are hollow. Web Plate and Flange Plate are flat pieces used to reinforce or connect parts of a beam, not hollow structural members themselves.
