CHS 76.2x1.55 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 76.2x1.55 steel profile weighs 2.9 kg/m (1.92 lb/ft). Cross-sectional area: 363.506 mm². Moment of inertia Ix = 25.332 cm⁴, Iy = 25.332 cm⁴.

Cross-section (not to scale)

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