CHS 76x8 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 76x8 steel profile weighs 13.4 kg/m (9.02 lb/ft). Cross-sectional area: 1,709.026 mm². Moment of inertia Ix = 100.149 cm⁴, Iy = 100.149 cm⁴.
