RHS 50x30x2.5 Acindar · Weight & Dimensions

Acindar, 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 50x30 cal 13 (México) · Caño estructural 50x30 (Argentina)

The RHS 50x30x2.5 steel profile weighs 2.8 kg/m (1.90 lb/ft), has a depth of 50 mm (1.97 in), flange width 30 mm (1.18 in). Cross-sectional area: 358.905 mm². Moment of inertia Ix = 11.298 cm⁴, Iy = 5.052 cm⁴.
