CHS 140x14 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 140x14 steel profile weighs 43.5 kg/m (29.23 lb/ft). Cross-sectional area: 5,541.769 mm². Moment of inertia Ix = 1,113.341 cm⁴, Iy = 1,113.341 cm⁴.
