Performance Longevity: Laboratory aging shows aluminum foil duct maintains ≥98% airflow after 12 years in use (source: SGS test report 2023-09, SGS).
Fire Retardance: Composite layers and metallurgical bonding meet UL/ISO fire safety standards.
Customizability: Can be shaped onsite; supports non-standard diameters, L/T-junctions, quick-connects.

4. Manufacturing Process: Aluminum Foil Duct Production Steps

Raw Aluminum Ingot ➡️ Hot/Casting Rolling ➡️ Annealing (650°C) ➡️ Slitting & Bonding ➡️ Spiral Wire Reinforcement ➡️ Forming & Expansion ➡️ Quality Control (ISO/SGS)

Raw Material Selection: High-purity (≥99.2%) aluminum ingots meeting ASTM B209/EN 573-3 standards.
Rolling & Annealing: Continuous rolling, followed by annealing to improve ductility—crucial for flexible aluminum foil duct fabrication.
Foil Slitting & Multi-layer Bonding: Thin foils (40–60μm) slit and pressed with non-toxic glue; custom layer counts (2–7-ply) per pressure/fire rating needs.
Spiral Wire Forming: Galvanized/high-grade steel wire coiled into helical ducts to support flexing and negative pressure loads.
Expansion, Shaping & Cutting: Duct expanded to rated diameter; length cut to spec with tolerance ±1%; both ends optionally beaded or capped for connection.
Testing/Quality Control: Each batch is tested per ISO 6944 (fire), EN 12237 (pressure), and ANSI/ASHRAE 62.1 (leakage/airflow loss).

9. Professional FAQ: Technical Terms & Industry Standards

Q1: What is the standard material composition of an aluminum foil duct? A1: Typically, it’s ≥99.2% pure aluminum (per ASTM B209) with multi-ply foil layers, often reinforced by spiral galvanized steel wire for shape retention and durability.

Q2: What certifications should a quality flexible aluminum foil duct have? A2: ISO 9001 Quality, UL 181 Class 1 (fire resistance), ISO 6944 for fire, RoHS and CE. Always ask for third-party report copies!

Q3: Which diameter/type is recommended for commercial kitchen range hoods? A3: Standard diameters are 150mm or 180mm. For high-flow hoods, use thicker, double-spiral reinforced types for sustained negative pressure handling. Check local code (e.g., ANSI/NFPA 96 for USA).

Q4: How is aluminium foil flexible duct installed and sealed? A4: Fit onto duct flanges, secure with worm-drive clamps, and seal joints with UL-approved foil tape. For best results, minimize sharp bends and avoid kinking.

Q5: What is the expected lifespan of a high-grade aluminum foil duct? A5: Over 15 years in standard conditions if meeting ASTM D573 and regularly inspected for integrity.

Q6: How does aluminum foil duct compare to PVC or steel in terms of chemical resistance? A6: Aluminum foil ducts outperform PVC in most acids and humid environments but offer less abrasion resistance than thick-wall steel. For kitchen, HVAC, and light industrial areas, aluminum offers an optimum balance.

Q7: Are there any environmental or recycling benefits? A7: Yes! Aluminum is 100% recyclable, and many suppliers (e.g., Kebinghose) use up to 38% recycled material per ISO 14021 - lowering embodied CO₂ compared to steel or plastic alternatives.
