RHS 100x50x5 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 100x50 cal 6 (México) · Caño estructural 100x50 (Argentina)

The RHS 100x50x5 steel profile weighs 10.8 kg/m (7.26 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,357.08 mm². Moment of inertia Ix = 163.441 cm⁴, Iy = 53.733 cm⁴.
