CHS 68x10 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 68x10 steel profile weighs 14.3 kg/m (9.61 lb/ft). Cross-sectional area: 1,822.124 mm². Moment of inertia Ix = 78.898 cm⁴, Iy = 78.898 cm⁴.
