CHS 139.7x5
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 139.7x5 steel profile weighs 16.6 kg/m (11.16 lb/ft). Cross-sectional area: 2,115.9 mm². Moment of inertia Ix = 480.54 cm⁴, Iy = 480.54 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
