CHS 51x2.6 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 51x2.6 steel profile weighs 3.1 kg/m (2.08 lb/ft). Cross-sectional area: 395.338 mm². Moment of inertia Ix = 11.61 cm⁴, Iy = 11.61 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.6 mm ≈ 12 gauge (Manufacturers Standard Gage)
