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%.
