CHS 219x8 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 219x8 steel profile weighs 41.6 kg/m (27.98 lb/ft). Cross-sectional area: 5,303.008 mm². Moment of inertia Ix = 2,955.433 cm⁴, Iy = 2,955.433 cm⁴.
