HSS8.625x.322 – HSS Shapes - Round

HSS8.625x.322 is an 8.625 in (219 mm) diameter round hollow section with a 0.322 in (8 mm) nominal wall, weighing 28.58 lb/ft (42.5 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.
