CHS 159x22 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 159x22 steel profile weighs 74.3 kg/m (49.95 lb/ft). Cross-sectional area: 9,468.76 mm². Moment of inertia Ix = 2,278.776 cm⁴, Iy = 2,278.776 cm⁴.
