Galvanized Spiral Duct

‌Galvanized Spiral Duct: Engineered for Superior Airflow Control‌

1. ‌Superior Durability‌

   • Hot-dip galvanized coating (Z275 standard) resists corrosion, extending lifespan to 25+ years even in harsh environments (e.g., coastal areas, chemical plants).

2. ‌Optimal Airflow Efficiency‌

   • Spiral-wound design reduces turbulence, achieving 15% lower pressure drop compared to rectangular ducts (SMACNA-tested).

3. ‌Lightweight & Easy Installation‌

   • Lock-seam joints enable tool-free assembly, cutting labor costs by 30%. Modular fittings (elbows, reducers) simplify retrofits.

4. ‌Fire & Hygiene Compliance‌

   • Meets EN 13501-1 fire ratings and ISO 14644 cleanroom standards for hospitals/labs.

5. ‌Smart-Ready‌

   • IoT sensor compatibility (pressure/temperature) for real-time HVAC monitoring via BIM integration.

6. ‌Cost-Effective Maintenance‌

   • Smooth interior surface minimizes dust accumulation, reducing cleaning frequency by 50%.

Applications‌

• ‌HVAC Systems‌: Ideal for commercial buildings, hospitals, and cleanrooms.
• ‌Industrial Ventilation‌: Handles corrosive fumes in factories/labs (e.g., chemical plants).
• ‌Fire-Rated Systems‌: Paired with fireproof insulation for smoke extraction.

Engineering Solutions‌

• ‌Seamless Construction‌: Spiral lock-seam technology eliminates leakage points.
• ‌Galvanized Coating‌: Zinc layer (≥Z275 grade) resists rust in humid environments.
• ‌Modular Fittings‌: Pre-fabricated elbows/reducers reduce installation time by 40%.

Advanced Technical Parameters‌

Smart Functionality‌

• ‌IoT Sensors‌: Optional airflow/pressure monitors for real-time system analytics.
• ‌BIM Integration‌: 3D models (Revit/DWG) available for precision planning.

Technical Notes‌

• ‌Installation Tip‌: Use neoprene gaskets at joints to prevent vibration noise.
