RHS 300x200x8
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 300x200x8 steel profile weighs 58.2 kg/m (39.11 lb/ft), has a depth of 300 mm (11.81 in), flange width 200 mm (7.87 in). Cross-sectional area: 7,744 mm². Moment of inertia Ix = 9,877 cm⁴, Iy = 5,256.84 cm⁴.
