CHS 219x14 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 219x14 steel profile weighs 70.8 kg/m (47.56 lb/ft). Cross-sectional area: 9,016.371 mm². Moment of inertia Ix = 4,758.502 cm⁴, Iy = 4,758.502 cm⁴.
