CHS 25.4x2.25 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 25.4x2.25 steel profile weighs 1.3 kg/m (0.86 lb/ft). Cross-sectional area: 163.638 mm². Moment of inertia Ix = 1.107 cm⁴, Iy = 1.107 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.25 mm ≈ 13 gauge (Manufacturers Standard Gage)
