CHS 194x18 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 194x18 steel profile weighs 78.1 kg/m (52.50 lb/ft). Cross-sectional area: 9,952.566 mm². Moment of inertia Ix = 3,893.941 cm⁴, Iy = 3,893.941 cm⁴.
