Steel Section Catalog
HSS 42.2x3.6
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 42.2x3.6 steel profile weighs 3.2 kg/m (2.12 lb/ft). Cross-sectional area: 403.3 mm². Moment of inertia Ix = 7.68 cm⁴, Iy = 7.68 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.3 mm ≈ 10 gauge (Manufacturers Standard Gage)
