Rectangular ducts are essential components in heating, ventilation, and air conditioning (HVAC) systems, commonly used for the efficient distribution of air within buildings. These ducts are typically made from galvanized steel, aluminum, or other durable materials, providing both strength and resistance to corrosion. Their rectangular shape offers several advantages, including ease of installation and the ability to fit into tight spaces such as ceiling voids and walls, making them ideal for both commercial and residential applications.

One of the key benefits of rectangular ducts is their ability to handle large volumes of air while maintaining a low profile. This design minimizes air resistance and allows for smooth airflow, which is crucial for maintaining consistent indoor temperatures and ensuring effective air circulation. Additionally, the flat surfaces of rectangular ducts make them easier to insulate, helping to improve energy efficiency by reducing heat loss or gain.

Rectangular ducts can be customized to fit specific design requirements, and their versatility makes them a popular choice in complex HVAC systems. Whether used for supply, return, or exhaust air, these ducts play a critical role in creating comfortable indoor environments by ensuring the efficient and reliable movement of air throughout a building.
