CHS 76.1x5
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 76.1x5 steel profile weighs 8.8 kg/m (5.89 lb/ft). Cross-sectional area: 1,116.8 mm². Moment of inertia Ix = 70.92 cm⁴, Iy = 70.92 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
