Galvanized Spiral Duct

  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%.

Galvanized Spiral Duct: Engineered for Superior Airflow Control

Galvanized spiral ducts‌ provide robust, corrosion-resistant ventilation solutions for demanding industrial and commercial environments. Their spiral-wound design ensures structural integrity while minimizing pressure loss. Below is a technical breakdown of their applications and advantages.


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%.
