CHS 26.9x2.3
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 26.9x2.3 steel profile weighs 1.4 kg/m (0.93 lb/ft). Cross-sectional area: 177.8 mm². Moment of inertia Ix = 1.36 cm⁴, Iy = 1.36 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.3 mm ≈ 13 gauge (Manufacturers Standard Gage)
