CHS 114x8 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 114x8 steel profile weighs 20.9 kg/m (14.05 lb/ft). Cross-sectional area: 2,664.071 mm². Moment of inertia Ix = 376.3 cm⁴, Iy = 376.3 cm⁴.
