CHS 245x17 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 245x17 steel profile weighs 95.6 kg/m (64.24 lb/ft). Cross-sectional area: 12,176.813 mm². Moment of inertia Ix = 7,956.482 cm⁴, Iy = 7,956.482 cm⁴.
