RHS 90x50x4 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 8 (México) · Caño estructural 90x50 (Argentina)

The RHS 90x50x4 steel profile weighs 8.0 kg/m (5.36 lb/ft), has a depth of 90 mm (3.54 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,014.796 mm². Moment of inertia Ix = 102.71 cm⁴, Iy = 40.707 cm⁴.
