CHS 42.2x3.18 CISC · Weight & Dimensions
CISC, 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 42.2x3.18 steel profile weighs 3.1 kg/m (2.06 lb/ft). Cross-sectional area: 389.82 mm². Moment of inertia Ix = 7.468 cm⁴, Iy = 7.468 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.18 mm ≈ 10 gauge (Manufacturers Standard Gage)
