CHS 63.5x1.5 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 63.5x1.5 steel profile weighs 2.3 kg/m (1.54 lb/ft). Cross-sectional area: 292.168 mm². Moment of inertia Ix = 14.047 cm⁴, Iy = 14.047 cm⁴.

Cross-section (not to scale)

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