CHS 76.1x3.2
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 76.1x3.2 steel profile weighs 5.8 kg/m (3.86 lb/ft). Cross-sectional area: 732.9 mm². Moment of inertia Ix = 48.78 cm⁴, Iy = 48.78 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.2 mm ≈ 10 gauge (Manufacturers Standard Gage)
