CHS 41.27x1.25 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 41.27x1.25 steel profile weighs 1.2 kg/m (0.83 lb/ft). Cross-sectional area: 157.158 mm². Moment of inertia Ix = 3.149 cm⁴, Iy = 3.149 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.25 mm ≈ 18 gauge (Manufacturers Standard Gage)
