RHS 90x30x2
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 90x30x2 steel profile weighs 3.5 kg/m (2.33 lb/ft), has a depth of 90 mm (3.54 in), flange width 30 mm (1.18 in). Cross-sectional area: 464 mm². Moment of inertia Ix = 44.44 cm⁴, Iy = 7.65 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
