Material: Galvanized iron spiral flat oval ducts are made from galvanized steel sheets that are formed into a flattened oval shape.
Advantages:
Corrosion Resistance: The zinc coating on galvanized iron provides excellent corrosion resistance, making it suitable for a variety of environments.
Space Efficiency: The flat oval shape maximizes space efficiency, making it ideal for installations with limited space.
Durability: Galvanized iron is known for its durability and longevity, ensuring a long service life.
Material: Galvanized iron spiral flat oval ducts are made from galvanized steel sheets that are formed into a flattened oval shape.

Material:Insulated spiral flat oval ducts are typically constructed with a galvanized iron or aluminum outer shell and include insulation material within the duct.
Advantages:
Thermal Insulation: The insulation layer helps maintain consistent temperatures and prevents condensation within the duct, making it suitable for both heating and cooling applications.
Energy Efficiency: Insulated spiral flat oval ducts reduce heat loss or gain, improving HVAC system efficiency.
Reduced Noise: The insulation layer can also provide sound attenuation, reducing noise transmission through the duct system.
