CHS 127x22 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 127x22 steel profile weighs 57.0 kg/m (38.28 lb/ft). Cross-sectional area: 7,257.079 mm². Moment of inertia Ix = 1,044.022 cm⁴, Iy = 1,044.022 cm⁴.
