RHS 90x50x6.3 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 90x50 cal 4 (México) · Caño estructural 90x50 (Argentina)

The RHS 90x50x6.3 steel profile weighs 12.3 kg/m (8.27 lb/ft), has a depth of 90 mm (3.54 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,537.1 mm². Moment of inertia Ix = 146.34 cm⁴, Iy = 56.244 cm⁴.
