Types of spiral duct

Spiral ducts in the market are generally divided into three categories according to their materials: galvanized spiral ducts, stainless steel spiral ducts and composite spiral ducts. Among them, stainless steel ducts have the best quality and strong applicability, but the price is high.

The most widely circulated spiral duct on the market is galvanized sheet. Galvanized spiral ducts are basically the characteristics of stainless steel spiral ducts, but the price is relatively only two-thirds or lower of stainless steel ducts. Composite spiral ducts are generally used in places where the external environment is relatively common and the requirements for ducts are not too high.
