CHS 108x3.6 Tecnometal · Weight & Dimensions
Tecnometal, cold-formed sections (Spain) · 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 108x3.6 steel profile weighs 9.3 kg/m (6.23 lb/ft). Cross-sectional area: 1,180.736 mm². Moment of inertia Ix = 161.057 cm⁴, Iy = 161.057 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.6 mm ≈ 9 gauge (Manufacturers Standard Gage)
