HSS7.5x.188 – HSS Shapes - Round

HSS7.5x.188 is a 7.5 in (191 mm) diameter round hollow section with a 0.188 in (5 mm) nominal wall, weighing 14.7 lb/ft (21.9 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.
