CHS 177.8x5 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 177.8x5 steel profile weighs 21.3 kg/m (14.29 lb/ft). Cross-sectional area: 2,714.336 mm². Moment of inertia Ix = 1,013.969 cm⁴, Iy = 1,013.969 cm⁴.

Cross-section (not to scale)

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