RHS 100x50x5
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 100x50x5 steel profile weighs 10.5 kg/m (7.06 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,400 mm². Moment of inertia Ix = 173.67 cm⁴, Iy = 56.17 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
