CHS 219x17 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 219x17 steel profile weighs 84.7 kg/m (56.91 lb/ft). Cross-sectional area: 10,788.229 mm². Moment of inertia Ix = 5,541.509 cm⁴, Iy = 5,541.509 cm⁴.
