CHS 76.1x2 Tuboeuropa · Weight & Dimensions

Tuboeuropa, 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 steel profile weighs 3.7 kg/m (2.46 lb/ft). Cross-sectional area: 465.584 mm². Moment of inertia Ix = 31.979 cm⁴, Iy = 31.979 cm⁴.

Cross-section (not to scale)

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