CHS 114.3x5 · Weight & Dimensions

EN — 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 114.3x5 steel profile weighs 13.5 kg/m (9.07 lb/ft). Cross-sectional area: 1,716.9 mm². Moment of inertia Ix = 256.92 cm⁴, Iy = 256.92 cm⁴.

Cross-section (not to scale)

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