RHS 90x50x3.2 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 90x50 cal 11 (México) · Caño estructural 90x50 (Argentina)

The RHS 90x50x3.2 steel profile weighs 6.5 kg/m (4.37 lb/ft), has a depth of 90 mm (3.54 in), flange width 50 mm (1.97 in). Cross-sectional area: 828.67 mm². Moment of inertia Ix = 86.267 cm⁴, Iy = 34.442 cm⁴.
