CHS 88.9x6 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 88.9x6 steel profile weighs 12.3 kg/m (8.23 lb/ft). Cross-sectional area: 1,562.628 mm². Moment of inertia Ix = 134.941 cm⁴, Iy = 134.941 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6 mm ≈ 4 gauge (Manufacturers Standard Gage)
