CHS 76x2 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 76x2 steel profile weighs 3.6 kg/m (2.45 lb/ft). Cross-sectional area: 464.956 mm². Moment of inertia Ix = 31.849 cm⁴, Iy = 31.849 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
