CHS 273x5.6 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 273x5.6 steel profile weighs 36.9 kg/m (24.82 lb/ft). Cross-sectional area: 4,704.347 mm². Moment of inertia Ix = 4,206.516 cm⁴, Iy = 4,206.516 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5.6 mm ≈ 4 gauge (Manufacturers Standard Gage)
