CHS 108x22 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 108x22 steel profile weighs 46.7 kg/m (31.36 lb/ft). Cross-sectional area: 5,943.893 mm². Moment of inertia Ix = 585.473 cm⁴, Iy = 585.473 cm⁴.
