RHS 80x60x2.5 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 80x60 cal 13 (México) · Caño estructural 80x60 (Argentina)

The RHS 80x60x2.5 steel profile weighs 5.2 kg/m (3.47 lb/ft), has a depth of 80 mm (3.15 in), flange width 60 mm (2.36 in). Cross-sectional area: 658.905 mm². Moment of inertia Ix = 60.126 cm⁴, Iy = 38.613 cm⁴.
