CHS 44.5x2.6 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 44.5x2.6 steel profile weighs 2.7 kg/m (1.81 lb/ft). Cross-sectional area: 342.245 mm². Moment of inertia Ix = 7.54 cm⁴, Iy = 7.54 cm⁴.

Cross-section (not to scale)

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