HSS10x10x5/8 (HSS10x10x.625) – HSS Shapes - Square

HSS10x10x5/8 is a 10 in (254 mm) square hollow section with a 5/8 in (16 mm) nominal wall, weighing 76.33 lb/ft (113.6 kg/m).

Square HSS (Hollow Structural Sections) are closed, tube-shaped sections with equal depth and width. The closed profile gives excellent torsional stiffness and identical strength about both axes, a meaningful advantage over open shapes such as W or C sections. That symmetry makes square HSS a natural choice for columns, particularly where architecturally exposed structural steel is part of the design, and for posts, bracing and light framing where equal biaxial capacity and a clean profile matter more than bending capacity in one direction.
