CHS 50x2.0 · 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 50x2.0 steel profile weighs 2.4 kg/m (1.59 lb/ft). Cross-sectional area: 301.6 mm². Moment of inertia Ix = 8.7 cm⁴, Iy = 8.7 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
