RHS 140x60x4 · Weight & Dimensions

BR — 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 140x60 cal 8 (México) · Caño estructural 140x60 (Argentina)

The RHS 140x60x4 steel profile weighs 11.7 kg/m (7.86 lb/ft), has a depth of 140 mm (5.51 in), flange width 60 mm (2.36 in). Cross-sectional area: 1,536 mm². Moment of inertia Ix = 375.35 cm⁴, Iy = 97.33 cm⁴.
