CHS 22.22x0.7 Acindar · Weight & Dimensions

Acindar, 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 22.22x0.7 steel profile weighs 0.4 kg/m (0.25 lb/ft). Cross-sectional area: 47.325 mm². Moment of inertia Ix = 0.274 cm⁴, Iy = 0.274 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 0.7 mm ≈ 18 gauge (Manufacturers Standard Gage)
