CHS 159x3 Condesa · Weight & Dimensions
Condesa, cold-formed sections · 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.
Also known as: Caño estructural redondo (Argentina)
The CHS 159x3 steel profile weighs 11.5 kg/m (7.75 lb/ft). Cross-sectional area: 1,470.265 mm². Moment of inertia Ix = 447.42 cm⁴, Iy = 447.42 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
