RHS 60x30x3 · 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 60x30 cal 11 (México) · Caño estructural 60x30 (Argentina)

The RHS 60x30x3 steel profile weighs 3.8 kg/m (2.54 lb/ft), has a depth of 60 mm (2.36 in), flange width 30 mm (1.18 in). Cross-sectional area: 504 mm². Moment of inertia Ix = 22.51 cm⁴, Iy = 7.28 cm⁴.
