CHS 108x16 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 108x16 steel profile weighs 36.3 kg/m (24.39 lb/ft). Cross-sectional area: 4,624.424 mm². Moment of inertia Ix = 504.062 cm⁴, Iy = 504.062 cm⁴.
