CHS 273x10 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 273x10 steel profile weighs 64.9 kg/m (43.59 lb/ft). Cross-sectional area: 8,262.389 mm². Moment of inertia Ix = 7,154.093 cm⁴, Iy = 7,154.093 cm⁴.
