CHS 89x22 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 89x22 steel profile weighs 36.4 kg/m (24.43 lb/ft). Cross-sectional area: 4,630.708 mm². Moment of inertia Ix = 287.856 cm⁴, Iy = 287.856 cm⁴.
