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.
Also known as: PTR 100x50 cal 6 (México) · Caño estructural 100x50 (Argentina)
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)
