CHS 146x17 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 146x17 steel profile weighs 54.1 kg/m (36.34 lb/ft). Cross-sectional area: 6,889.513 mm². Moment of inertia Ix = 1,457.993 cm⁴, Iy = 1,457.993 cm⁴.
