CHS 60.3x4.78 CISC · Weight & Dimensions

CISC, 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 60.3x4.78 steel profile weighs 6.5 kg/m (4.39 lb/ft). Cross-sectional area: 833.733 mm². Moment of inertia Ix = 32.363 cm⁴, Iy = 32.363 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.78 mm ≈ 7 gauge (Manufacturers Standard Gage)
