CHS 88.9x2.9 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 88.9x2.9 steel profile weighs 6.2 kg/m (4.13 lb/ft). Cross-sectional area: 783.513 mm². Moment of inertia Ix = 72.518 cm⁴, Iy = 72.518 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.9 mm ≈ 11 gauge (Manufacturers Standard Gage)
