CHS 26.9x2.6 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 26.9x2.6 steel profile weighs 1.6 kg/m (1.04 lb/ft). Cross-sectional area: 198.486 mm². Moment of inertia Ix = 1.482 cm⁴, Iy = 1.482 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.6 mm ≈ 12 gauge (Manufacturers Standard Gage)
