CHS 50x7 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 50x7 steel profile weighs 7.4 kg/m (4.99 lb/ft). Cross-sectional area: 945.619 mm². Moment of inertia Ix = 22.435 cm⁴, Iy = 22.435 cm⁴.
