CHS 68x11 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 68x11 steel profile weighs 15.5 kg/m (10.39 lb/ft). Cross-sectional area: 1,969.779 mm². Moment of inertia Ix = 82.977 cm⁴, Iy = 82.977 cm⁴.
