RHS 300x100x5 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 300x100 cal 6 (México) · Caño estructural 300x100 (Argentina)

The RHS 300x100x5 steel profile weighs 30.4 kg/m (20.43 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 3,857.08 mm². Moment of inertia Ix = 4,113.205 cm⁴, Iy = 728.024 cm⁴.
