What Is Stainless Steel Ductwork?

Stainless steel ductwork generally refers to HVAC ducting components made of stainless steel, although the term is sometimes erroneously used to refer to larger, galvanized steel ducts. Stainless steel ductwork is more common in commercial and industrial settings than in residential settings due to its high cost but superior durability.

Galvanized steel costs less than stainless steel, as of 2015, but provides comparable protection against corrosion typical in HVAC systems, making it the most popular choice for ductwork in residential settings. Aluminum is a popular choice as well due to its even lower cost; aluminum's flexibility also makes it easy to use for custom designs.
