CHS 63x11 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 63x11 steel profile weighs 14.1 kg/m (9.48 lb/ft). Cross-sectional area: 1,796.991 mm². Moment of inertia Ix = 63.456 cm⁴, Iy = 63.456 cm⁴.
