CHS 57x10 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 57x10 steel profile weighs 11.6 kg/m (7.79 lb/ft). Cross-sectional area: 1,476.549 mm². Moment of inertia Ix = 42.617 cm⁴, Iy = 42.617 cm⁴.
