CHS 76x1.5 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 76x1.5 steel profile weighs 2.8 kg/m (1.85 lb/ft). Cross-sectional area: 351.073 mm². Moment of inertia Ix = 24.367 cm⁴, Iy = 24.367 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
