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.
The CHS 89x12 steel profile weighs 22.8 kg/m (15.31 lb/ft). Cross-sectional area: 2,902.832 mm². Moment of inertia Ix = 220.361 cm⁴, Iy = 220.361 cm⁴.
