Steel Section Catalog
HSS 73.0x5.2
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 73.0x5.2 steel profile weighs 8.1 kg/m (5.44 lb/ft). Cross-sectional area: 1,028.4 mm². Moment of inertia Ix = 60.09 cm⁴, Iy = 60.09 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.8 mm ≈ 7 gauge (Manufacturers Standard Gage)
