RHS 70x40x3.2 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 70x40 cal 11 (México) · Caño estructural 70x40 (Argentina)

The RHS 70x40x3.2 steel profile weighs 5.0 kg/m (3.36 lb/ft), has a depth of 70 mm (2.76 in), flange width 40 mm (1.57 in). Cross-sectional area: 636.67 mm². Moment of inertia Ix = 39.183 cm⁴, Iy = 16.239 cm⁴.
