CHS 50x10 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 50x10 steel profile weighs 9.9 kg/m (6.63 lb/ft). Cross-sectional area: 1,256.637 mm². Moment of inertia Ix = 26.704 cm⁴, Iy = 26.704 cm⁴.
