CHS 83x3.5 Hiasa · Weight & Dimensions
Hiasa, 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 83x3.5 steel profile weighs 6.9 kg/m (4.61 lb/ft). Cross-sectional area: 874.148 mm². Moment of inertia Ix = 69.194 cm⁴, Iy = 69.194 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.5 mm ≈ 10 gauge (Manufacturers Standard Gage)
