CHS 457.2x6.3 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 457.2x6.3 steel profile weighs 70.1 kg/m (47.08 lb/ft). Cross-sectional area: 8,924.228 mm². Moment of inertia Ix = 22,684.328 cm⁴, Iy = 22,684.328 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
