CHS 323.9x25 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 323.9x25 steel profile weighs 184.3 kg/m (123.84 lb/ft). Cross-sectional area: 23,475.551 mm². Moment of inertia Ix = 26,400.08 cm⁴, Iy = 26,400.08 cm⁴.
