Production Line
Designed for efficient production of round downspout pipes, this roll forming line delivers stable shaping, clean cutting, and consistent profiles for residential and commercial drainage systems.
- Reduced material waste
- Lower production costs
- Easy daily operation
We can customize the production line for different metal roofing gutter and downspout designs, including profile dimensions, material thickness ranges, embossing patterns, and punching requirements.
Recommended for gutter system manufacturers, roofing accessory suppliers, and contractors requiring economical, stable, and continuous production of standard round downspout pipes for construction projects.

Profile Information
Half-round gutters are used for roof rainwater drainage. Their curved shape improves water flow efficiency and appearance, with multiple diameter options for residential and commercial buildings.
Half-round gutters are commonly produced from 0.4-0.8mm galvanized steel, aluminum, or color-coated steel because these materials provide corrosion resistance, durability, and good outdoor weather performance.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 3/5/7/10 Ton | Expanding Range | 460-50mm |
Roll Forming Machine
The wall-panel chain-drive roll forming machine gradually shapes flat steel coils into round downspout profiles through multiple forming stations.
This economical configuration offers stable transmission, simple maintenance, and reliable production for standard gutter drainage products. Gearbox-driven structures are also available for higher-duty production requirements.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Hydraulic Cut
The hydraulic stop-to-cut system cuts formed profiles to preset lengths after roll forming. During cutting, the machine temporarily stops to prevent profile movement and ensure cleaner cutting accuracy. For customers requiring higher production speed, flying shear or non-stop cutting solutions can also be customized.
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer 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 standard configuration operates at 15–20 m/min. Higher-end configurations can reach 30–40 m/min, and even higher speeds can be customized according to specific production requirements.
Lead times range from 30-50 days post-order, varying by customization level and supplier location. We typically require 45 days for standard machines.
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.
