CHS 146x28 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 146x28 steel profile weighs 81.5 kg/m (54.75 lb/ft). Cross-sectional area: 10,379.822 mm². Moment of inertia Ix = 1,908.33 cm⁴, Iy = 1,908.33 cm⁴.
