CHS 273x36 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 273x36 steel profile weighs 210.4 kg/m (141.40 lb/ft). Cross-sectional area: 26,804.069 mm². Moment of inertia Ix = 19,253.697 cm⁴, Iy = 19,253.697 cm⁴.
