CHS 76x12 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 76x12 steel profile weighs 18.9 kg/m (12.73 lb/ft). Cross-sectional area: 2,412.743 mm². Moment of inertia Ix = 127.875 cm⁴, Iy = 127.875 cm⁴.
