The downspout pipe roll forming machine is an automated production line designed for manufacturing metal downspouts used in roof drainage systems. The machine integrates decoiling, roll forming, bending, cutting, and run-out handling into one continuous process, ensuring high efficiency and consistent product quality.
As a reliable downspout machine manufacturer, DUWELL designs and supplies customized downspout roll forming machines suitable for different materials, sizes, and profiles. Operators only need to set the required length and quantity on the PLC controller, and the system runs automatically with stable output.
Optional in-line or separate bending units can be configured depending on production requirements and factory layout. If you are interested in our downspout pipe roll forming machines, please contact us today.
As an experienced downspout machine manufacturer, DUWELL provides complete production solutions for both residential and commercial rainwater drainage systems. Each downspout pipe roll forming machine is engineered according to the customer’s material thickness, profile drawings, and output capacity requirements.
The system is widely used by:
Gutter and downspout manufacturers
Roofing system suppliers
Building material factories
Construction component producers
It can be combined with gutter roll forming machine to create a complete rainwater drainage production line.
Round Downspouts
Round downspouts are the standard first choice for a half round gutter system installation but are also compatible with box-style and k-style gutters There are two primary round downspout styles to consider: Plain Round or Round Corrugated both are circular in shape, however, Round Corrugated, also called Fluted Downspouts have corrugations/flutes that provide extra strength as well as conceal dents over time.
Round downspouts are available in a range of sizes and finishes. The diameter can be 3, 4, 5, or 6" and they come in painted aluminum, mill finish aluminum, copper, galvanized, galvalume. We make the machines according to customer’s requirement.
Rectangular Downspouts
Rectangular downspouts are typically used with k style and box style gutter systems; although they can be used with half round gutter systems. Since they are roll formed through a downspout machine they have corrugations. These corrugations strengthen the downspout and add additional rigidity. Mostly used sizes are 2x3, 3x4, and 4x5. We make the downspout making machine according to customer's required sizes and material.
