CHS 140x16 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 140x16 steel profile weighs 48.9 kg/m (32.88 lb/ft). Cross-sectional area: 6,232.92 mm². Moment of inertia Ix = 1,217.913 cm⁴, Iy = 1,217.913 cm⁴.
