CHS 26.9x3.2 Tata Steel · Weight & Dimensions

Tata Steel, 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 26.9x3.2 steel profile weighs 1.9 kg/m (1.26 lb/ft). Cross-sectional area: 238.258 mm². Moment of inertia Ix = 1.703 cm⁴, Iy = 1.703 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.2 mm ≈ 10 gauge (Manufacturers Standard Gage)
