CHS 95x20 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 95x20 steel profile weighs 37.0 kg/m (24.86 lb/ft). Cross-sectional area: 4,712.389 mm². Moment of inertia Ix = 354.902 cm⁴, Iy = 354.902 cm⁴.
