Steel Section Catalog
HSS 219.1x6.4
AISC — 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 HSS 219.1x6.4 steel profile weighs 31.0 kg/m (20.83 lb/ft). Cross-sectional area: 3,951.7 mm². Moment of inertia Ix = 2,247.01 cm⁴, Iy = 2,247.01 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5.9 mm ≈ 4 gauge (Manufacturers Standard Gage)
