CHS 76.2x1.1 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 76.2x1.1 steel profile weighs 2.0 kg/m (1.37 lb/ft). Cross-sectional area: 259.527 mm². Moment of inertia Ix = 18.301 cm⁴, Iy = 18.301 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.1 mm ≈ 18 gauge (Manufacturers Standard Gage)
