CHS 83x17 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 83x17 steel profile weighs 27.7 kg/m (18.59 lb/ft). Cross-sectional area: 3,524.867 mm². Moment of inertia Ix = 204.663 cm⁴, Iy = 204.663 cm⁴.
