CHS 63x8 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 63x8 steel profile weighs 10.8 kg/m (7.29 lb/ft). Cross-sectional area: 1,382.301 mm². Moment of inertia Ix = 53.374 cm⁴, Iy = 53.374 cm⁴.
