RHS 200x100x5
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 200x100x5 steel profile weighs 22.0 kg/m (14.78 lb/ft), has a depth of 200 mm (7.87 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,900 mm². Moment of inertia Ix = 1,522.42 cm⁴, Iy = 512.42 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
