CHS 203x32 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 203x32 steel profile weighs 134.9 kg/m (90.69 lb/ft). Cross-sectional area: 17,190.795 mm². Moment of inertia Ix = 6,503.493 cm⁴, Iy = 6,503.493 cm⁴.
