HSS 76x76x4.8
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 76x76x4.8 steel profile weighs 9.9 kg/m (6.65 lb/ft), has a depth of 76.2 mm (3.00 in), flange width 76.2 mm (3.00 in). Cross-sectional area: 1,290.6 mm². Moment of inertia Ix = 111.02 cm⁴, Iy = 111.02 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.5 mm ≈ 7 gauge (Manufacturers Standard Gage)
