CHS 60.3x6.4 Açotubo · Weight & Dimensions

Açotubo, cold-formed sections · 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 60.3x6.4 steel profile weighs 8.5 kg/m (5.72 lb/ft). Cross-sectional area: 1,083.724 mm². Moment of inertia Ix = 39.91 cm⁴, Iy = 39.91 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 6.4 mm ≈ 3 gauge (Manufacturers Standard Gage)
