HSS8x8x3/16 (HSS8x8x.1875) – HSS Shapes - Square

HSS8x8x3/16 is an 8 in (203 mm) square hollow section with a 3/16 in (5 mm) nominal wall, weighing 19.63 lb/ft (29.2 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.
