CHS 57.15x1.5 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 57.15x1.5 steel profile weighs 2.1 kg/m (1.38 lb/ft). Cross-sectional area: 262.244 mm². Moment of inertia Ix = 10.159 cm⁴, Iy = 10.159 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.5 mm ≈ 16 gauge (Manufacturers Standard Gage)
