CHS 15.87x0.8 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 15.87x0.8 steel profile weighs 0.3 kg/m (0.20 lb/ft). Cross-sectional area: 37.875 mm². Moment of inertia Ix = 0.108 cm⁴, Iy = 0.108 cm⁴.

Cross-section (not to scale)

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