CHS 168x14 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 168x14 steel profile weighs 53.2 kg/m (35.73 lb/ft). Cross-sectional area: 6,773.274 mm². Moment of inertia Ix = 2,024.532 cm⁴, Iy = 2,024.532 cm⁴.
