RHS 30x20x2
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 30x20x2 steel profile weighs 1.4 kg/m (0.91 lb/ft), has a depth of 30 mm (1.18 in), flange width 20 mm (0.79 in). Cross-sectional area: 184 mm². Moment of inertia Ix = 2.16 cm⁴, Iy = 1.11 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
