CHS 168x17 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 168x17 steel profile weighs 63.3 kg/m (42.54 lb/ft). Cross-sectional area: 8,064.468 mm². Moment of inertia Ix = 2,327.607 cm⁴, Iy = 2,327.607 cm⁴.
