CHS 245x22 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 245x22 steel profile weighs 121.0 kg/m (81.31 lb/ft). Cross-sectional area: 15,412.654 mm². Moment of inertia Ix = 9,673.945 cm⁴, Iy = 9,673.945 cm⁴.
