CHS 146x22 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 146x22 steel profile weighs 67.3 kg/m (45.21 lb/ft). Cross-sectional area: 8,570.265 mm². Moment of inertia Ix = 1,699.055 cm⁴, Iy = 1,699.055 cm⁴.
