RHS 160x80x3
BR — 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 RHS 160x80x3 steel profile weighs 10.7 kg/m (7.19 lb/ft), has a depth of 160 mm (6.30 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,404 mm². Moment of inertia Ix = 478.44 cm⁴, Iy = 162.63 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
