Steel Section Catalog
HSS 60.3x3.9
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 60.3x3.9 steel profile weighs 5.0 kg/m (3.38 lb/ft). Cross-sectional area: 641.3 mm². Moment of inertia Ix = 25.87 cm⁴, Iy = 25.87 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.6 mm ≈ 9 gauge (Manufacturers Standard Gage)
