CHS 219x28 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 219x28 steel profile weighs 131.9 kg/m (88.63 lb/ft). Cross-sectional area: 16,801.238 mm². Moment of inertia Ix = 7,826.226 cm⁴, Iy = 7,826.226 cm⁴.
