CHS 219x30 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 219x30 steel profile weighs 139.8 kg/m (93.97 lb/ft). Cross-sectional area: 17,812.83 mm². Moment of inertia Ix = 8,154.046 cm⁴, Iy = 8,154.046 cm⁴.
