CHS 101.6x1.6 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 101.6x1.6 steel profile weighs 4.0 kg/m (2.65 lb/ft). Cross-sectional area: 502.655 mm². Moment of inertia Ix = 62.848 cm⁴, Iy = 62.848 cm⁴.

Cross-section (not to scale)

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