CHS 76.1x4
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 76.1x4 steel profile weighs 7.1 kg/m (4.78 lb/ft). Cross-sectional area: 906 mm². Moment of inertia Ix = 59.06 cm⁴, Iy = 59.06 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
