CHS 15.87x1.9 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 15.87x1.9 steel profile weighs 0.7 kg/m (0.44 lb/ft). Cross-sectional area: 83.387 mm². Moment of inertia Ix = 0.207 cm⁴, Iy = 0.207 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.9 mm ≈ 14 gauge (Manufacturers Standard Gage)
