CHS 108x5 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 108x5 steel profile weighs 12.7 kg/m (8.53 lb/ft). Cross-sectional area: 1,617.92 mm². Moment of inertia Ix = 215.062 cm⁴, Iy = 215.062 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 5 mm ≈ 6 gauge (Manufacturers Standard Gage)
