CHS 63.5x2.65 Gerdau · Weight & Dimensions

Gerdau, tubes · 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 63.5x2.65 steel profile weighs 4.0 kg/m (2.67 lb/ft). Cross-sectional area: 506.59 mm². Moment of inertia Ix = 23.491 cm⁴, Iy = 23.491 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.65 mm ≈ 12 gauge (Manufacturers Standard Gage)
