CHS 245x8 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 245x8 steel profile weighs 46.8 kg/m (31.42 lb/ft). Cross-sectional area: 5,956.46 mm². Moment of inertia Ix = 4,186.87 cm⁴, Iy = 4,186.87 cm⁴.
