In the era of green buildings and energy-efficient HVAC systems, Spiral Duct Machines have become a hot topic across the global construction and ventilation industry. With stricter energy codes and higher standards for indoor air quality, contractors are shifting towards spiral ductwork for its superior performance and long-term value.

Compared to rectangular ducts, spiral ducts offer less air leakage, lower pressure loss, and easier installation—making them the preferred choice in commercial, industrial, and cleanroom projects. As demand rises, manufacturers are seeking reliable and automated solutions to produce high-quality spiral ducts quickly and efficiently.

At Hecheng Source Machinery, our Spiral Duct Machines are designed to meet these evolving needs. Our machines can process galvanized steel, stainless steel, and aluminum, supporting multiple diameters and thicknesses. With PLC control, fast forming speed, and durable structure, our equipment is ideal for high-volume production.
