CHS 33.7x2.3 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Spain) · 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 33.7x2.3 steel profile weighs 1.8 kg/m (1.20 lb/ft). Cross-sectional area: 226.886 mm². Moment of inertia Ix = 2.811 cm⁴, Iy = 2.811 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.3 mm ≈ 13 gauge (Manufacturers Standard Gage)
