RHS 50x40x2
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 50x40x2 steel profile weighs 2.6 kg/m (1.73 lb/ft), has a depth of 50 mm (1.97 in), flange width 40 mm (1.57 in). Cross-sectional area: 344 mm². Moment of inertia Ix = 12.47 cm⁴, Iy = 8.78 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
