RHS 50x30x3.2 Tata Steel Celsius · Weight & Dimensions

Tata Steel Celsius · 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 11 (México) · Caño estructural 50x30 (Argentina)

The RHS 50x30x3.2 steel profile weighs 3.6 kg/m (2.43 lb/ft), has a depth of 50 mm (1.97 in), flange width 30 mm (1.18 in). Cross-sectional area: 453.46 mm². Moment of inertia Ix = 13.917 cm⁴, Iy = 6.118 cm⁴.
