CHS 245x10 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 245x10 steel profile weighs 58.0 kg/m (38.94 lb/ft). Cross-sectional area: 7,382.743 mm². Moment of inertia Ix = 5,105.628 cm⁴, Iy = 5,105.628 cm⁴.
