CHS 63.5x5.6 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 63.5x5.6 steel profile weighs 8.0 kg/m (5.38 lb/ft). Cross-sectional area: 1,018.63 mm². Moment of inertia Ix = 43.085 cm⁴, Iy = 43.085 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5.6 mm ≈ 4 gauge (Manufacturers Standard Gage)
