RHS 100x50x3.2 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 100x50 cal 11 (México) · Caño estructural 100x50 (Argentina)

The RHS 100x50x3.2 steel profile weighs 7.0 kg/m (4.71 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 892.67 mm². Moment of inertia Ix = 112.291 cm⁴, Iy = 37.951 cm⁴.
