CHS 76.1x2.5 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 76.1x2.5 steel profile weighs 4.5 kg/m (3.05 lb/ft). Cross-sectional area: 578.053 mm². Moment of inertia Ix = 39.186 cm⁴, Iy = 39.186 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
