RHS 400x200x10
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 400x200x10 steel profile weighs 86.6 kg/m (58.20 lb/ft), has a depth of 400 mm (15.75 in), flange width 200 mm (7.87 in). Cross-sectional area: 11,600 mm². Moment of inertia Ix = 24,358.67 cm⁴, Iy = 8,198.67 cm⁴.
