In response to increasing demands for safety, flexibility, and installation efficiency in ventilation and industrial systems, a new generation of Aluminum Semi-Rigid Duct has been introduced to the market. Made of high-quality soft aluminum foil, this duct combines self-holding strength with excellent flexibility, making it ideal for low and medium pressure air conditioning, ventilation, boiler systems, and chimney liners.

• Flexible & Self-Holding Construction
  The duct maintains its shape during installation without requiring additional supports, adapting easily to tight or complex spaces. With an extension rate of 1:3, it offers exceptional on-site adaptability.

• Wide Temperature & Pressure Range
  Operating temperature spans from -25°C to +300°C, suitable for boiler exhaust, chimney liners, industrial ventilation, and HVAC systems. Maximum airflow velocity reaches 30 m/s, with a working pressure rating of 2500 Pa for medium and low pressure systems.

• Fire Safety – No Toxic Gas Release
  The duct is rated non-flammable and releases no toxic gases even at high temperatures, meeting strict fire safety standards for public buildings and industrial facilities.

• Versatile Specifications

  • Diameter range: 50–500mm (2” – 20”)

  • Aluminum thickness: 0.08mm – 0.12mm

  • Corrugation options: 3, 5, or 9

  • Standard lengths: 1.5m, 3.0m, 6m

• HVAC supply and return air ducts

• Medium/low pressure industrial exhaust and fume systems

• Boiler system flue gas pipes

• Chimney liner retrofitting and repairs

• Ventilation in ships, trains, and clean rooms

Compared to traditional galvanized iron ducts and standard flexible ducts, this aluminum semi-rigid duct offers clear benefits in weight reduction, labor cost savings, corrosion resistance, and high-temperature safety. It is especially valuable for projects requiring fast deployment, complex routing, or limited installation space.

“Modern buildings and industries need more than just air movement — they require safety, durability, and installation efficiency. This aluminum semi-rigid duct is designed exactly for that,” said the product technical lead.

The product is now available for bulk orders, with customization options for diameter, length, and corrugation type. Samples and technical support are available upon request.
