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 76x50x3.2 steel profile weighs 5.7 kg/m (3.81 lb/ft), has a depth of 76.2 mm (3.00 in), flange width 50.8 mm (2.00 in). Cross-sectional area: 726 mm². Moment of inertia Ix = 58.15 cm⁴, Iy = 30.65 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
