HSS 508.0x12.7
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 508.0x12.7 steel profile weighs 144.0 kg/m (96.77 lb/ft). Cross-sectional area: 18,394.5 mm². Moment of inertia Ix = 56,644.49 cm⁴, Iy = 56,644.49 cm⁴.
