Why Choose Precision Spiral Systems?

A spiral duct is a type of round duct formed from a metal strip coiled into a spiral seam. Unlike traditional rectangular ductwork, spiral ducts are circular in cross-section and provide advantages in airflow efficiency and strength.

✅ Advantages:

  • Lower air resistance (better airflow performance)
  • Less leakage than rectangular ducts
  • Stronger and more rigid due to spiral seam
  • Quieter operation
  • Aesthetically pleasing for exposed ductwork (industrial/modern design)
