RHS 150x100x8
EN — 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.
The RHS 150x100x8 steel profile weighs 27.4 kg/m (18.41 lb/ft), has a depth of 150 mm (5.91 in), flange width 100 mm (3.94 in). Cross-sectional area: 3,744 mm². Moment of inertia Ix = 1,128.23 cm⁴, Iy = 588.15 cm⁴.
