CHS 83x14 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 83x14 steel profile weighs 23.8 kg/m (16.01 lb/ft). Cross-sectional area: 3,034.779 mm². Moment of inertia Ix = 188.042 cm⁴, Iy = 188.042 cm⁴.
