CHS 114.3x4 · 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 114.3x4 steel profile weighs 10.9 kg/m (7.32 lb/ft). Cross-sectional area: 1,386.1 mm². Moment of inertia Ix = 211.07 cm⁴, Iy = 211.07 cm⁴.

Cross-section (not to scale)

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