CHS 63x14 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 63x14 steel profile weighs 16.9 kg/m (11.37 lb/ft). Cross-sectional area: 2,155.133 mm². Moment of inertia Ix = 69.961 cm⁴, Iy = 69.961 cm⁴.
