CHS 159x14 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 159x14 steel profile weighs 50.1 kg/m (33.64 lb/ft). Cross-sectional area: 6,377.433 mm². Moment of inertia Ix = 1,691.694 cm⁴, Iy = 1,691.694 cm⁴.
