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 30x1.5 steel profile weighs 1.1 kg/m (0.71 lb/ft). Cross-sectional area: 134.3 mm². Moment of inertia Ix = 1.37 cm⁴, Iy = 1.37 cm⁴.
