CHS 180x22 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 180x22 steel profile weighs 85.7 kg/m (57.60 lb/ft). Cross-sectional area: 10,920.176 mm². Moment of inertia Ix = 3,473.708 cm⁴, Iy = 3,473.708 cm⁴.
