CISC, cold-formed sections · Circular Hollow Section
Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.
The CHS 114.3x4.78 steel profile weighs 12.9 kg/m (8.68 lb/ft). Cross-sectional area: 1,644.641 mm². Moment of inertia Ix = 247.056 cm⁴, Iy = 247.056 cm⁴.
