RHS 120x60x5 · Weight & Dimensions

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 120x60 cal 6 (México) · Caño estructural 120x60 (Argentina)

The RHS 120x60x5 steel profile weighs 12.8 kg/m (8.60 lb/ft), has a depth of 120 mm (4.72 in), flange width 60 mm (2.36 in). Cross-sectional area: 1,700 mm². Moment of inertia Ix = 309.42 cm⁴, Iy = 101.42 cm⁴.
