RHS 20x15x2 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 20x15 cal 15 (México) · Caño estructural 20x15 (Argentina)

The RHS 20x15x2 steel profile weighs 0.9 kg/m (0.60 lb/ft), has a depth of 20 mm (0.79 in), flange width 15 mm (0.59 in). Cross-sectional area: 113.699 mm². Moment of inertia Ix = 0.529 cm⁴, Iy = 0.333 cm⁴.
