CHS 76x11 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 76x11 steel profile weighs 17.6 kg/m (11.85 lb/ft). Cross-sectional area: 2,246.239 mm². Moment of inertia Ix = 122.027 cm⁴, Iy = 122.027 cm⁴.
