CHS 90x2.5 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 90x2.5 steel profile weighs 5.4 kg/m (3.62 lb/ft). Cross-sectional area: 687.223 mm². Moment of inertia Ix = 65.823 cm⁴, Iy = 65.823 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
