CHS 22.22x2 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 22.22x2 steel profile weighs 1.0 kg/m (0.67 lb/ft). Cross-sectional area: 127.046 mm². Moment of inertia Ix = 0.656 cm⁴, Iy = 0.656 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
