CHS 102x2.5 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 102x2.5 steel profile weighs 6.1 kg/m (4.12 lb/ft). Cross-sectional area: 781.471 mm². Moment of inertia Ix = 96.771 cm⁴, Iy = 96.771 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
