CHS 457x40 Iberian tables · Weight & Dimensions

Iberian tables, cold-formed sections · 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 457x40 steel profile weighs 411.4 kg/m (276.43 lb/ft). Cross-sectional area: 52,401.765 mm². Moment of inertia Ix = 114,949.168 cm⁴, Iy = 114,949.168 cm⁴.
