Steel Section Catalog
HSS 273.1x6.4
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 273.1x6.4 steel profile weighs 38.8 kg/m (26.07 lb/ft). Cross-sectional area: 4,952.7 mm². Moment of inertia Ix = 4,422.14 cm⁴, Iy = 4,422.14 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5.9 mm ≈ 4 gauge (Manufacturers Standard Gage)
