What type of sheet metal is not part of HVAC?

Explanation:
In HVAC work, sheet metal choices are driven by what will carry and handle air—ducts, fittings, and components that need to meet airflow and ductwork codes. Architectural sheet metal, on the other hand, is used for building finishes—decorative panels, cornices, flashing, gutters, roofing, and other envelope elements. It isn’t formed or rated for duct systems or air handling, so it isn’t part of HVAC. The other metals listed—copper, aluminum, and stainless—are commonly used in HVAC components for reasons like formability, weight, cost, and corrosion resistance, depending on the application. That’s why architectural sheet metal is the one that isn’t part of HVAC.
