CHS 42x3.56 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 42x3.56 steel profile weighs 3.4 kg/m (2.26 lb/ft). Cross-sectional area: 429.916 mm². Moment of inertia Ix = 8.009 cm⁴, Iy = 8.009 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.56 mm ≈ 9 gauge (Manufacturers Standard Gage)
