CHS 70x5 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 70x5 steel profile weighs 8.0 kg/m (5.38 lb/ft). Cross-sectional area: 1,021.018 mm². Moment of inertia Ix = 54.242 cm⁴, Iy = 54.242 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
