HSS 406x406x9.5

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 406x406x9.5 steel profile weighs 104.0 kg/m (69.89 lb/ft), has a depth of 406.4 mm (16.00 in), flange width 406.4 mm (16.00 in). Cross-sectional area: 13,995.5 mm². Moment of inertia Ix = 36,892.94 cm⁴, Iy = 36,892.94 cm⁴.
