Flexible duct wire

Bekaert steel wire for flexible ducts features tight diameter tolerance. This feature enables a smooth coiling process of a consistent helix. The wire’s superior formability allows for a smaller bending radius. It enables the production of flexible spiral cores for complex layouts and narrow spaces. The polyurethane coating provides optimal protection against corrosion and thermal fluctuations.
