Steel Section Catalog
HSS 141.3x6.6
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 141.3x6.6 steel profile weighs 20.3 kg/m (13.64 lb/ft). Cross-sectional area: 2,590.9 mm². Moment of inertia Ix = 593.2 cm⁴, Iy = 593.2 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.1 mm ≈ 4 gauge (Manufacturers Standard Gage)
