Features of Round Plain Ducts:

• Shape: As the name suggests, round plain ducts are round in shape, which allows for efficient airflow and reduces air turbulence and noise.
• Material: Round plain ducts are typically made of galvanized steel or aluminum, which are both strong and resistant to corrosion.
• Sizes: Round plain ducts come in a range of sizes, from a few inches in diameter to several feet, to accommodate different HVAC system needs.
• Joint connections: Round plain ducts can be joined together using a variety of methods, including flanges, slip joints, and drive connectors. The joints are sealed to prevent air leaks and ensure efficient airflow.
