HSS 305x305x8.0

AISC — Square Hollow Section

Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.

The HSS 305x305x8.0 steel profile weighs 66.5 kg/m (44.69 lb/ft), has a depth of 304.8 mm (12.00 in), flange width 304.8 mm (12.00 in). Cross-sectional area: 8,803 mm². Moment of inertia Ix = 12,984.71 cm⁴, Iy = 12,984.71 cm⁴.
