RHS 120x60x4
EN — 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 120x60x4 steel profile weighs 10.5 kg/m (7.06 lb/ft), has a depth of 120 mm (4.72 in), flange width 60 mm (2.36 in). Cross-sectional area: 1,376 mm². Moment of inertia Ix = 255.2 cm⁴, Iy = 84.77 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
