CHS 60.3x3.9 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Brazil) · 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 60.3x3.9 steel profile weighs 5.4 kg/m (3.64 lb/ft). Cross-sectional area: 691.025 mm². Moment of inertia Ix = 27.608 cm⁴, Iy = 27.608 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.9 mm ≈ 9 gauge (Manufacturers Standard Gage)
