Production Line
This square downspout pipe elbowing machine performs precise bending and one-end swaging, enabling fast connection of rainwater downspout elbows with stable dimensions and clean assembly results.
- Fast elbow production
- Tight pipe connection
- Reduced manual assembly
- Improved installation efficiency
The production line configuration can be customized according to different square downspout dimensions, bending angles, connection designs, material thicknesses, and regional rainwater drainage standards.
Recommended for gutter and rainwater system manufacturers, building material suppliers, and metal drainage component producers requiring efficient elbow forming and reliable pipe connection performance.
Profile Information
Square downspout pipes are used for roof rainwater drainage. Their square or rectangular shape provides modern appearance, stable wall installation, and compatibility with various architectural drainage systems.
Square downspout pipes are commonly produced from 0.4-0.8mm galvanized steel, color-coated steel, aluminum, or copper because these materials offer corrosion resistance, outdoor durability, and attractive surface appearance.
How Does The Roll Forming Machine Work?
Machine Details
Elbow Forming Function
The elbow forming section is designed to bend square downspout pipes into precise drainage angles while maintaining stable profile dimensions and smooth corner appearance.
Hydraulic or servo-controlled forming improves bending consistency, reduces deformation, and ensures better installation alignment compared with manual processing methods.
One-End Neck Shrinking Function
The one-end neck shrinking section reduces one pipe end diameter for direct overlap connection with standard square downspout pipes.
This process improves assembly efficiency, creates tighter pipe joints, and reduces installation gaps. Optional tooling is available for different pipe sizes and connection requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
The machine is suitable for galvanized steel, pre-painted steel, aluminum, and some copper materials commonly used in rainwater drainage systems.
Lead times range from 10-20 days post-order, varying by customization level and supplier location. We typically require 15 days for standard machines.
The machine can produce common elbow angles such as 30°, 45°, 72°, and 90°, depending on customer drainage system requirements and tooling configuration.
Different bending radiuses can be achieved through customized tooling designs based on project requirements and local installation preferences.
There is no need to worry. Our machines are designed for easy installation and operation.
Before shipment, we will finish the main assembly and testing in our factory. When the machine arrives, you only need to place it in position, connect the power supply, and it can start working.
We will also provide:
detailed installation and operation manuals
machine layout drawings
wiring diagrams
online technical support (video call / photos / videos)
If needed, we can also arrange an engineer to come to your factory to help with installation and training. Many of our customers complete installation smoothly with our online guidance.
30% deposit is paid before production, the balance paid after inspection confrmation, before shipment.
