RHS 120x80x4 Iberian tables · Weight & Dimensions

Iberian tables, 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 120x80 cal 8 (México) · Caño estructural 120x80 (Argentina)

The RHS 120x80x4 steel profile weighs 11.7 kg/m (7.88 lb/ft), has a depth of 120 mm (4.72 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,494.796 mm². Moment of inertia Ix = 294.585 cm⁴, Iy = 157.294 cm⁴.
