CHS 194x10 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 194x10 steel profile weighs 45.4 kg/m (30.50 lb/ft). Cross-sectional area: 5,780.53 mm². Moment of inertia Ix = 2,453.546 cm⁴, Iy = 2,453.546 cm⁴.
