CHS 127x2.25 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 127x2.25 steel profile weighs 6.9 kg/m (4.65 lb/ft). Cross-sectional area: 881.806 mm². Moment of inertia Ix = 171.595 cm⁴, Iy = 171.595 cm⁴.

Cross-section (not to scale)

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