CHS 141x6.55 IMCA · Weight & Dimensions
IMCA, 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 141x6.55 steel profile weighs 21.7 kg/m (14.60 lb/ft). Cross-sectional area: 2,766.636 mm². Moment of inertia Ix = 626.633 cm⁴, Iy = 626.633 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.55 mm ≈ 3 gauge (Manufacturers Standard Gage)
