CHS 50.8x0.8 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 50.8x0.8 steel profile weighs 1.0 kg/m (0.67 lb/ft). Cross-sectional area: 125.664 mm². Moment of inertia Ix = 3.928 cm⁴, Iy = 3.928 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 0.8 mm ≈ 18 gauge (Manufacturers Standard Gage)
