RHS 38x50x1.5
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 38x50x1.5 steel profile weighs 2.0 kg/m (1.35 lb/ft), has a depth of 38 mm (1.50 in), flange width 50 mm (1.97 in). Cross-sectional area: 255 mm². Moment of inertia Ix = 6.07 cm⁴, Iy = 9.3 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
