CHS 114.3x6.3
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 114.3x6.3 steel profile weighs 16.8 kg/m (11.29 lb/ft). Cross-sectional area: 2,137.5 mm². Moment of inertia Ix = 312.71 cm⁴, Iy = 312.71 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
