HSS9.625x.312 – HSS Shapes - Round

HSS9.625x.312 is a 9.625 in (244 mm) diameter round hollow section with a 0.312 in (8 mm) nominal wall, weighing 31.06 lb/ft (46.2 kg/m).

Round HSS are closed, circular tube sections, sharing the torsional and biaxial strength advantages of rectangular HSS but in a circular profile that's often preferred where appearance matters — exposed columns, canopy supports, and architectural framing — as well as more utilitarian uses like handrail posts and bollards. The circular shape distributes compressive and torsional loads evenly in every direction, making round HSS a strong, materially efficient choice wherever a round column or post is wanted rather than a square or rectangular one.
