CHS 323.9x7.1 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 323.9x7.1 steel profile weighs 55.5 kg/m (37.28 lb/ft). Cross-sectional area: 7,066.322 mm². Moment of inertia Ix = 8,869.351 cm⁴, Iy = 8,869.351 cm⁴.
