RHS 15x30x1.5
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 15x30x1.5 steel profile weighs 1.0 kg/m (0.66 lb/ft), has a depth of 15 mm (0.59 in), flange width 30 mm (1.18 in). Cross-sectional area: 126 mm². Moment of inertia Ix = 0.45 cm⁴, Iy = 1.41 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
