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 73x17 steel profile weighs 23.5 kg/m (15.78 lb/ft). Cross-sectional area: 2,990.796 mm². Moment of inertia Ix = 128.043 cm⁴, Iy = 128.043 cm⁴.
