CHS 140x25 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 140x25 steel profile weighs 70.9 kg/m (47.64 lb/ft). Cross-sectional area: 9,032.079 mm². Moment of inertia Ix = 1,563.679 cm⁴, Iy = 1,563.679 cm⁴.
