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)
