CHS 203x10 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 203x10 steel profile weighs 47.6 kg/m (31.99 lb/ft). Cross-sectional area: 6,063.274 mm². Moment of inertia Ix = 2,830.715 cm⁴, Iy = 2,830.715 cm⁴.
