RHS 50x30x5 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 50x30 cal 6 (México) · Caño estructural 50x30 (Argentina)

The RHS 50x30x5 steel profile weighs 5.3 kg/m (3.55 lb/ft), has a depth of 50 mm (1.97 in), flange width 30 mm (1.18 in). Cross-sectional area: 657.08 mm². Moment of inertia Ix = 18.15 cm⁴, Iy = 7.764 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
