CHS 146x25 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 146x25 steel profile weighs 74.6 kg/m (50.13 lb/ft). Cross-sectional area: 9,503.318 mm². Moment of inertia Ix = 1,813.471 cm⁴, Iy = 1,813.471 cm⁴.
