CHS 140x20 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 140x20 steel profile weighs 59.2 kg/m (39.78 lb/ft). Cross-sectional area: 7,539.822 mm². Moment of inertia Ix = 1,394.867 cm⁴, Iy = 1,394.867 cm⁴.
