CHS 63.5x3.35 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 63.5x3.35 steel profile weighs 5.0 kg/m (3.34 lb/ft). Cross-sectional area: 633.039 mm². Moment of inertia Ix = 28.718 cm⁴, Iy = 28.718 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.35 mm ≈ 10 gauge (Manufacturers Standard Gage)
