CHS 26x1.55 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 26x1.55 steel profile weighs 0.9 kg/m (0.62 lb/ft). Cross-sectional area: 119.059 mm². Moment of inertia Ix = 0.893 cm⁴, Iy = 0.893 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.55 mm ≈ 16 gauge (Manufacturers Standard Gage)
