HSS 102x76x4.8
AISC — Rectangular Hollow Section
Rectangular Hollow Sections (RHS) are tubular profiles with excellent torsional resistance and aesthetic appeal. Used for columns, trusses, and exposed structural elements.
The HSS 102x76x4.8 steel profile weighs 11.7 kg/m (7.86 lb/ft), has a depth of 101.6 mm (4.00 in), flange width 76.2 mm (3.00 in). Cross-sectional area: 1,519.2 mm². Moment of inertia Ix = 221.32 cm⁴, Iy = 140.43 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.5 mm ≈ 7 gauge (Manufacturers Standard Gage)
