Round GI Duct Work


Round GI (Galvanized Iron) duct work is an essential component in modern HVAC systems, widely used for air distribution, ventilation, and exhaust applications. Fabricated from galvanized iron sheets, these ducts are durable, rust-resistant, and capable of withstanding different environmental conditions. Their circular or spiral shape ensures smooth airflow with minimal resistance, making them more efficient compared to traditional rectangular ducts.

One of the key advantages of round GI ducts is their strength and rigidity, which allows them to maintain shape and performance even under higher air pressure. They require fewer joints and sealing materials, reducing the chances of leakage and ensuring cost-effectiveness in both installation and long-term operation. The smooth inner surface also makes cleaning and maintenance easier.

Round GI duct work is commonly applied in commercial buildings, residential projects, and industrial facilities, where it serves for air conditioning, fresh air supply, kitchen exhaust, and mechanical ventilation. When installed properly with appropriate supports, gaskets, and insulation, round GI ducts provide a reliable and efficient solution for healthy indoor air quality.
