CHS 273x14 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 273x14 steel profile weighs 89.4 kg/m (60.09 lb/ft). Cross-sectional area: 11,391.415 mm². Moment of inertia Ix = 9,579.753 cm⁴, Iy = 9,579.753 cm⁴.
