CHS 203x22 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 203x22 steel profile weighs 98.2 kg/m (65.99 lb/ft). Cross-sectional area: 12,509.822 mm². Moment of inertia Ix = 5,198.613 cm⁴, Iy = 5,198.613 cm⁴.
