CHS 159x28 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 159x28 steel profile weighs 90.5 kg/m (60.79 lb/ft). Cross-sectional area: 11,523.362 mm². Moment of inertia Ix = 2,584.834 cm⁴, Iy = 2,584.834 cm⁴.
