The spiral oval duct is commonly used in various applications, especially in HVAC (Heating, Ventilation, and Air Conditioning) systems, due to its unique combination of efficiency and versatility.

Material:

The Spiral Flat Oval Duct is typically made from galvanized steel due to its durability and corrosion resistance. In some cases, aluminum or stainless steel may also be used, depending on the application and environmental factors.

Strength:

The spiral seam construction provides excellent structural integrity, ensuring that the duct can handle internal pressures and stresses from the airflow. The continuous spiral seam offers increased strength compared to traditional seams, making the duct more resistant to deformations and leaks.

Corrosion Resistance:

Galvanized steel is coated with a layer of zinc, providing a high level of corrosion resistance, especially in humid or damp environments. Aluminum ducts, which are sometimes used for specific applications, are also naturally resistant to corrosion.

Fabrication:

Spiral seam flat oval ducts are fabricated by winding a metal sheet into a spiral shape, with the seam securely joined, often by mechanically crimping or using spiral-lock technology.

Applications:

Commercial HVAC systems in office buildings, malls, and industrial spaces where space efficiency is a priority. Residential applications for homes with limited ceiling or wall clearance. Often used in underfloor air distribution systems, ceiling plenums, or tight vertical spaces, thanks to their compact shape.

Cost-Effectiveness:

While spiral seam flat oval ducts might have a slightly higher initial cost compared to standard round ducts, their long-term cost-effectiveness comes from their durability and efficiency. Their strength and durability lead to lower maintenance and repair costs.

Maintenance:

Low Maintenance: Due to the robust materials (such as galvanized steel) and the strong spiral seam construction, these ducts typically require minimal maintenance.
