CHS 114x9 GOST · Weight & Dimensions

GOST, 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 114x9 steel profile weighs 23.3 kg/m (15.66 lb/ft). Cross-sectional area: 2,968.805 mm². Moment of inertia Ix = 412.144 cm⁴, Iy = 412.144 cm⁴.
