CHS 168x22 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 168x22 steel profile weighs 79.2 kg/m (53.23 lb/ft). Cross-sectional area: 10,090.796 mm². Moment of inertia Ix = 2,749.742 cm⁴, Iy = 2,749.742 cm⁴.
