RHS 60x20x0.9 Acindar · Weight & Dimensions

Acindar, cold-formed sections · 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 60x20 cal 18 (México) · Caño estructural 60x20 (Argentina)

The RHS 60x20x0.9 steel profile weighs 1.1 kg/m (0.73 lb/ft), has a depth of 60 mm (2.36 in), flange width 20 mm (0.79 in). Cross-sectional area: 138.674 mm². Moment of inertia Ix = 5.915 cm⁴, Iy = 1.056 cm⁴.
