CHS 273x4 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 273x4 steel profile weighs 26.5 kg/m (17.83 lb/ft). Cross-sectional area: 3,380.354 mm². Moment of inertia Ix = 3,058.248 cm⁴, Iy = 3,058.248 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
