What is a common type of HVAC ductwork material?

Galvanized steel is a common type of HVAC ductwork material due to its durability and resistance to corrosion. This material has excellent structural integrity, allowing it to maintain its shape even under pressure from airflow, which is essential for efficient air distribution in HVAC systems.

Additionally, galvanized steel is widely available and cost-effective, making it a popular choice among contractors and builders. Its smooth inner surface minimizes friction losses, enhancing airflow efficiency and reducing energy consumption.

While aluminum also serves as a ductwork material and offers lightweight benefits, galvanized steel is often favored in commercial applications for its strength and longevity. Plastic ductwork, though it is used in certain situations, is less prevalent in traditional HVAC installations due to limitations in holding up under high temperatures. Copper, while excellent for refrigerant lines due to its conductivity, is not typically used for ductwork that distributes air, making it an uncommon choice for this specific purpose.
