CHS 90x4 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 90x4 steel profile weighs 8.5 kg/m (5.70 lb/ft). Cross-sectional area: 1,080.708 mm². Moment of inertia Ix = 100.128 cm⁴, Iy = 100.128 cm⁴.

Cross-section (not to scale)

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