EN — 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 30x2.0 steel profile weighs 1.4 kg/m (0.93 lb/ft). Cross-sectional area: 175.9 mm². Moment of inertia Ix = 1.73 cm⁴, Iy = 1.73 cm⁴.
