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 300x200x10 steel profile weighs 71.2 kg/m (47.85 lb/ft), has a depth of 300 mm (11.81 in), flange width 200 mm (7.87 in). Cross-sectional area: 9,600 mm². Moment of inertia Ix = 12,072 cm⁴, Iy = 6,392 cm⁴.
