CHS 140x11 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 140x11 steel profile weighs 35.0 kg/m (23.51 lb/ft). Cross-sectional area: 4,457.92 mm². Moment of inertia Ix = 934.046 cm⁴, Iy = 934.046 cm⁴.
