Frequently Asked Question
Rectangular ductwork is commonly called rectangular air ducting or rectangular HVAC ductwork. It is used to distribute conditioned air throughout commercial, industrial and residential buildings.
Rectangular ductwork is generally made by cutting and forming galvanized steel, stainless steel or other suitable sheet metal according to the required dimensions. The sheets are folded, joined and sealed to create strong, airtight duct sections. Proper sizing and fabrication depend on airflow requirements and HVAC system design.
The cost depends on the material, size, installation requirements and project design. Round ducts can often require less material and may be economical for certain applications, while rectangular ducts are preferred where space constraints or building layouts require specific dimensions. A proper comparison should consider both manufacturing and installation costs.
Rectangular duct size is calculated based on the required airflow (CFM), desired air velocity, and available installation space. First, determine the required duct cross-sectional area using the airflow and target velocity, then select suitable width and height dimensions. Final sizing should also consider pressure loss, duct length, fittings, and HVAC design requirements.
The rectangular duct size for 1200 CFM depends on the desired air velocity and system design. For example, a duct around 20 × 14 inches provides approximately 1.94 sq. ft. of area and can handle 1200 CFM at about 620 FPM. The final duct dimensions should be confirmed based on the complete HVAC system, pressure drop, noise requirements, and available space.
Yes, our rectangular ducts are fabricated in accordance with SMACNA-based duct construction practices, ensuring dimensional accuracy, structural strength, and reliable long-term performance.
