CHS 83x16 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 83x16 steel profile weighs 26.4 kg/m (17.77 lb/ft). Cross-sectional area: 3,367.787 mm². Moment of inertia Ix = 199.752 cm⁴, Iy = 199.752 cm⁴.
