RHS 50x25x3.2 Tata Steel · Weight & Dimensions

Tata Steel, 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 50x25 cal 11 (México) · Caño estructural 50x25 (Argentina)

The RHS 50x25x3.2 steel profile weighs 3.2 kg/m (2.18 lb/ft), has a depth of 50 mm (1.97 in), flange width 25 mm (0.98 in). Cross-sectional area: 412.67 mm². Moment of inertia Ix = 11.628 cm⁴, Iy = 3.802 cm⁴.
