CHS 120x3 Condesa · Weight & Dimensions

Condesa, 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 120x3 steel profile weighs 8.6 kg/m (5.80 lb/ft). Cross-sectional area: 1,102.699 mm². Moment of inertia Ix = 188.81 cm⁴, Iy = 188.81 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
