CHS 60.3x4.4 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 60.3x4.4 steel profile weighs 6.1 kg/m (4.08 lb/ft). Cross-sectional area: 772.706 mm². Moment of inertia Ix = 30.369 cm⁴, Iy = 30.369 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.4 mm ≈ 7 gauge (Manufacturers Standard Gage)
