CHS 219.1x6.3
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 219.1x6.3 steel profile weighs 33.1 kg/m (22.24 lb/ft). Cross-sectional area: 4,211.7 mm². Moment of inertia Ix = 2,386.14 cm⁴, Iy = 2,386.14 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
