Product Description
Galvanized spiral duct is a type of cylindrical ventilation duct used in HVAC (Heating, Ventilation, and Air Conditioning) systems, manufactured from galvanized steel. The galvanizing process involves applying a protective zinc coating to the steel surface, which provides corrosion resistance and durability. Galvanized spiral ducts are commonly used for efficient and long-lasting ductwork in commercial, industrial, and residential settings.

The ducts are constructed from galvanized steel, which has been coated with a layer of zinc. This galvanized coating provides excellent corrosion resistance, making the ducts suitable for use in various environments, including those with high humidity or moisture.
Strict Quality Control
Galvanized spiral ducts come in a variety of sizes and diameters to accommodate different HVAC system requirements and building layouts.
Packing and Delivery
Galvanized spiral ducts can be manufactured with various seam types, including lock-seam and spiral-seam. Lock-seam ducts have a tight, interlocking seam that provides durability and prevents air leakage. Spiral-seam ducts have a spiral lock seam that also ensures airtightness.
