Reduce Costs and Increase Efficiency
with Aluminum or Stainless Spiral Duct

Rolled Metal Products stocks all the standard thicknesses of stainless and aluminum coil specifically to slit for your spiral ductwork needs. There are several benefits to choosing spiral duct over rectangular duct for your applications. Their architectural appeal isn’t the only reason why spiral duct has taken center stage as the HVAC ductwork of choice. They’re efficient and help reduce both the manufacturing costs and the costs of installation.

BENEFITS OF STAINLESS SPIRAL DUCT

COST EFFECTIVE

Spiral duct can reduce costs by up to 50% compared to rectangular duct. Factors that can affect the cost include labor, material and aesthetic requirements. Because the round system is lightweight, up to 40% less compared to a rectangular system, it takes fewer support components and significantly less time to install and seal.

Air leakage on the joints and seams on rectangular ductwork is a typical issue that prompts vitality and proficiency misfortune due to holes and poor connections (up to 20-30%). This results in less air being distributed throughout the building or facility, increasing the system’s overall costs.
With spiral duct, the smooth, round design creates fewer locations for air to leak through while also equalizing the internal air pressure. This produces smooth, fast airflow throughout the ductwork and into the building 鈥 ultimately reducing costs.

HIGHER EFFICIENCY

REDUCED NOISE

Air moving through rectangular ducts is forced to move around edges, turning vanes, and dampers, reducing airflow and creates noise and vibrations. The smooth edges of stainless spiral duct eliminates unnecessary noise issues, creating a quieter, more efficient system.
