CHS 63.5x2.9 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 63.5x2.9 steel profile weighs 4.3 kg/m (2.91 lb/ft). Cross-sectional area: 552.103 mm². Moment of inertia Ix = 25.402 cm⁴, Iy = 25.402 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.9 mm ≈ 11 gauge (Manufacturers Standard Gage)
