CHS 219x16 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 219x16 steel profile weighs 80.1 kg/m (53.83 lb/ft). Cross-sectional area: 10,203.893 mm². Moment of inertia Ix = 5,288.805 cm⁴, Iy = 5,288.805 cm⁴.
