The Double-Unit Fence Rail Roll Forming Machine is an automatic cold roll forming production line designed for manufacturing metal fence rails, fencing profiles, and other customized cold-formed steel sections.
The machine adopts an integrated double-unit structure, combining two independent forming systems on one main machine frame. Each forming unit is equipped with its own forming shafts, rollers, transmission structure, guiding system, and forming channel.
The two forming units can be designed according to two different fence rail profiles and can operate independently without interfering with each other.
This structure is particularly suitable for manufacturers that regularly produce two different fence rail profiles. Compared with installing two completely separate roll forming machines, the double-unit design helps optimize workshop space while maintaining the production capability of two independent forming systems.
The complete production line can be equipped with decoiling, feeding, guiding, roll forming, hydraulic cutting, encoder length measurement, PLC control, and finished product receiving systems.
Two independent roll forming systems are installed on one integrated machine frame.
Each forming unit can be equipped with different forming rollers and designed according to a different fence rail profile.
This arrangement provides greater production flexibility while reducing the overall space required in the workshop.
The two forming units can be designed for two different fence rail or fencing profile sections.
Operators can select the corresponding forming unit according to the production order without frequently replacing a complete set of forming rollers.
This makes the machine especially suitable for manufacturers producing multiple fence profile models.
Each forming unit has its own forming shafts, rollers, and transmission structure.
The two systems can operate independently without affecting each other's forming process.
Depending on the final machine configuration, flexible production arrangements can also be designed according to the customer's production requirements.
The machine is equipped with a PLC and touch-screen control system.
The operator can set:
After the required parameters are entered, the production line can operate automatically.
The forming rollers are designed according to the actual profile section.
The steel strip gradually takes shape through multiple forming stations until the required final profile is achieved.
A properly designed forming process helps reduce deformation and improve the dimensional consistency of the finished product.
The machine can be customized according to the customer's:
The complete forming process and machine configuration are designed according to the actual product requirements.

Note: Final machine specifications are determined according to the customer's profile drawing, material specifications, and production requirements.
Decoiling → Feeding → Guiding → Roll Forming → Length Measuring → Hydraulic Cutting → Finished Product
If punching is required, the production line can be configured as:
Decoiling → Leveling → Punching → Feeding → Guiding → Roll Forming → Length Measuring → Cutting → Finished Product
The final production process will be designed according to the customer's actual profile drawing and processing requirements.
The decoiler is used to support and unwind the steel coil and continuously feed material into the roll forming machine.
Depending on the coil weight and production requirements, different decoiler options can be provided:
The guiding device ensures that the steel strip enters the forming system in the correct position.
Proper feeding alignment helps prevent material deviation and improves the dimensional accuracy of the finished profile.
The guiding system can be adjusted according to the material width.
The double-unit forming section is the core part of the production line.
The main machine includes two independent forming systems.
Each forming unit consists of:
The two units can be designed for two different fence rail profiles.
The forming rollers are professionally designed according to the customer's profile drawing.
The steel strip passes through a series of forming rollers and is gradually formed into the required final shape.
Different roller surface treatments can be selected according to the project requirements to improve wear resistance and service life.
The machine can use different transmission systems depending on the machine structure and production requirements.
Common options include:
A stable transmission system helps maintain synchronized operation of the forming shafts during continuous production.
When the formed profile reaches the preset length, the PLC sends a cutting signal to the hydraulic cutting system.
The profile is then automatically cut to the required length.
This reduces manual measurement and improves production efficiency and length consistency.
The production line is controlled by a PLC and touch-screen interface.
Operators can control and set:
The control interface is simple and convenient for daily production management.
The encoder continuously measures the moving length of the finished profile.
Once the preset product length is reached, the PLC automatically sends a signal to the cutting system.
This allows automatic fixed-length production.
The machine can be designed for processing different types of cold-forming steel materials, including:
Standard material thickness: 0.8–1.2 mm
The final material specification should be confirmed according to the profile section, steel strength, and finished product requirements.
The machine is mainly suitable for manufacturing:
Special profile sections can also be produced through customized machine design.
The Double-Unit Fence Rail Roll Forming Machine is suitable for:
For manufacturers that regularly produce two different fence profiles, the traditional solution is usually to install two separate roll forming machines.
The double-unit machine integrates two independent forming shaft and roller systems into one main machine frame.
Each forming system still maintains its own independent forming structure and production capability.
The main advantages include:
Because the machine still requires two separate sets of forming shafts, rollers, transmission components, and other core mechanical parts, its manufacturing cost is naturally higher than that of a standard single-unit roll forming machine.
To prepare an accurate machine solution, customers are recommended to provide the following information.
Based on this information, our technical team will design:
After manufacturing is completed, the machine will be assembled and tested before shipment.
Testing includes:
If customers can provide the actual steel material that will be used in production, we recommend testing and adjusting the machine with the customer's real material.
This allows the machine settings to better match actual production conditions.
The electrical control system can be configured according to customer requirements.
The main components include:
The machine voltage can be customized according to the industrial power supply standard in the customer's country.
For example:
380V / 50Hz / 3 Phase
Other voltage standards are also available according to project requirements.
During normal production, the operator first loads the steel coil onto the decoiler and feeds the material into the guiding and forming system.
The required production parameters are then entered into the PLC touch screen, including:
After the machine starts, the production line can automatically complete:
Feeding → Roll Forming → Length Measuring → Cutting → Finished Product
The automatic production process helps reduce manual operation and improve production efficiency.
After machine testing is completed, the equipment will be prepared for transportation.
Typical protection measures include:
Transportation options include:
The final shipping plan will be determined according to the machine dimensions, machine weight, and destination.
