RHS 60x40x3 · 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 60x40 cal 11 (México) · Caño estructural 60x40 (Argentina)

The RHS 60x40x3 steel profile weighs 4.3 kg/m (2.86 lb/ft), has a depth of 60 mm (2.36 in), flange width 40 mm (1.57 in). Cross-sectional area: 564 mm². Moment of inertia Ix = 27.39 cm⁴, Iy = 14.31 cm⁴.
