CHS 273.0x6.3
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 273.0x6.3 steel profile weighs 41.4 kg/m (27.82 lb/ft). Cross-sectional area: 5,278.5 mm². Moment of inertia Ix = 4,695.82 cm⁴, Iy = 4,695.82 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
