CHS 63x3.5 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 63x3.5 steel profile weighs 5.1 kg/m (3.45 lb/ft). Cross-sectional area: 654.237 mm². Moment of inertia Ix = 29.052 cm⁴, Iy = 29.052 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.5 mm ≈ 10 gauge (Manufacturers Standard Gage)
