CHS 53.97x0.9 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 53.97x0.9 steel profile weighs 1.2 kg/m (0.79 lb/ft). Cross-sectional area: 150.052 mm². Moment of inertia Ix = 5.284 cm⁴, Iy = 5.284 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 0.9 mm ≈ 18 gauge (Manufacturers Standard Gage)
