CHS 140x17 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 140x17 steel profile weighs 51.6 kg/m (34.66 lb/ft). Cross-sectional area: 6,569.07 mm². Moment of inertia Ix = 1,266.024 cm⁴, Iy = 1,266.024 cm⁴.
