CHS 50.8x1.6 Acindar · Weight & Dimensions

Acindar, 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 50.8x1.6 steel profile weighs 1.9 kg/m (1.30 lb/ft). Cross-sectional area: 247.306 mm². Moment of inertia Ix = 7.491 cm⁴, Iy = 7.491 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.6 mm ≈ 16 gauge (Manufacturers Standard Gage)
