CHS 194x11 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 194x11 steel profile weighs 49.6 kg/m (33.36 lb/ft). Cross-sectional area: 6,324.026 mm². Moment of inertia Ix = 2,656.881 cm⁴, Iy = 2,656.881 cm⁴.
