CHS 76.1x2.9 Iberian tables · Weight & Dimensions

Iberian tables, 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 76.1x2.9 steel profile weighs 5.2 kg/m (3.52 lb/ft). Cross-sectional area: 666.897 mm². Moment of inertia Ix = 44.738 cm⁴, Iy = 44.738 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.9 mm ≈ 11 gauge (Manufacturers Standard Gage)
