  • Product Description
  • On the market, spiral ducts are generally categorized into three types based on material: galvanized spiral ducts, stainless steel spiral ducts, and composite spiral ducts. Among these, stainless steel ducts offer the best quality and versatility, but they come at a higher price. Currently, the most widely available spiral duct on the market is the galvanized steel spiral duct, which largely shares the characteristics of stainless steel ducts yet costs only two-thirds or even less than stainless steel ducts. Composite spiral ducts are typically used in environments that are relatively ordinary and do not place particularly high demands on duct performance.
