CHS 168x12 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 168x12 steel profile weighs 46.2 kg/m (31.03 lb/ft). Cross-sectional area: 5,881.061 mm². Moment of inertia Ix = 1,799.605 cm⁴, Iy = 1,799.605 cm⁴.
