CHS 245x28 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 245x28 steel profile weighs 149.8 kg/m (100.69 lb/ft). Cross-sectional area: 19,088.317 mm². Moment of inertia Ix = 11,422.687 cm⁴, Iy = 11,422.687 cm⁴.
