HSS6x6x1/4 (HSS6x6x.25) – HSS Shapes - Square

HSS6x6x1/4 is a 6 in (152 mm) square hollow section with a 1/4 in (6 mm) nominal wall, weighing 19.02 lb/ft (28.3 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.
