CHS 63.5x3.75 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 63.5x3.75 steel profile weighs 5.5 kg/m (3.72 lb/ft). Cross-sectional area: 703.913 mm². Moment of inertia Ix = 31.536 cm⁴, Iy = 31.536 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.75 mm ≈ 9 gauge (Manufacturers Standard Gage)
