The spiral structure promotes smooth airflow with minimal pressure loss, making them ideal for both residential and commercial ventilation applications. Round Spiral Ducts, commonly used in air conditioning and ventilation systems, are valued for their high structural strength and rigidity.
GFI HVAC ensures each duct is precisely formed and tightly sealed to minimize air leakage and maximize system efficiency.
Since entering the HVAC industry in 2011, GFI HVAC has evolved from a trading company into a fully integrated manufacturer, continuously investing in advanced production facilities to expand our capabilities. This transformation has enabled us to develop extensive expertise in the manufacturing of spiral ducts, covering a wide range of specifications and applications in modern air duct systems.
Compared to rectangular ducts, spiral ducts offer superior strength, reduced air leakage, and easier installation, making them an ideal choice for modern HVAC systems. In addition, our flexible manufacturing allows for a wide variety of sizes, shapes, and connection options, supporting both standard and customized project requirements.
GFI HVAC manufactures spiral ducts primarily from galvanized steel and stainless steel materials, utilizing precision forming and automated welding technologies. Our advanced production processes include coil feeding, continuous forming, automatic seam locking, and customized cutting - ensuring consistent product quality and tight dimensional tolerances.
At GFI HVAC, we are dedicated to providing reliable and high-performance spiral duct solutions, backed by years of industry experience and a commitment to manufacturing excellence. Whether you require standard specifications or tailored configurations, our comprehensive production capabilities ensure fast, accurate, and cost-effective delivery for your HVAC projects.
Since 2011, GFI HVAC has been dedicated to the HVAC industry, beginning with galvanized duct (GI duct) and pre-insulated duct manufacturing. Over the past 13 years, we have steadily expanded our operations, establishing and investing in new production facilities to enhance our capabilities.
Today, GFI HVAC operates three duct production line(GI Duct, Spiral Duct, PID Duct) and a dedicated manufacturing site for air vents and dampers. Additionally, we have strategically invested in rubber insulation and flexible duct factories, further strengthening our ability to provide integrated solutions for HVAC projects.
Beyond factories and workers, we also have well-established trade and logistics departments. In business management, GFI HVAC values humanity and shared beliefs. We firmly believe that GFI HVAC is not just a manufacturer but a company driven by human-centric values and a strong collective vision.
