CHS 63.5x3 Cintac · Weight & Dimensions

Cintac, 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 63.5x3 steel profile weighs 4.5 kg/m (3.01 lb/ft). Cross-sectional area: 570.199 mm². Moment of inertia Ix = 26.153 cm⁴, Iy = 26.153 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3 mm ≈ 11 gauge (Manufacturers Standard Gage)
