CHS 63.5x4.25 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 63.5x4.25 steel profile weighs 6.2 kg/m (4.17 lb/ft). Cross-sectional area: 791.092 mm². Moment of inertia Ix = 34.893 cm⁴, Iy = 34.893 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.25 mm ≈ 8 gauge (Manufacturers Standard Gage)
