Steel Section Catalog
HSS 101.6x5.7
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 101.6x5.7 steel profile weighs 12.6 kg/m (8.47 lb/ft). Cross-sectional area: 1,603.4 mm². Moment of inertia Ix = 186.44 cm⁴, Iy = 186.44 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5.3 mm ≈ 6 gauge (Manufacturers Standard Gage)
