Strut Channel Production Line Configuration – Decoiler
The decoiler is the first unit in a Strut Channel Production Line. Its main function is to hold the steel coil and provide stable material feeding for the roll forming process.
A basic option is a manual decoiler (non-powered decoiler). The coil expansion and braking force are adjusted manually, which makes operation simple but limits production efficiency, especially for long-time continuous production.
For professional Strut Channel Roll Forming Machines, we usually recommend a hydraulic decoiler. Compared with a manual type, a 3-ton hydraulic decoiler normally increases the equipment cost by around USD 4,000–5,000. However, it provides faster coil loading, automatic expansion, and more stable feeding, which improves overall production efficiency and reduces labor requirements in long-term operation.
Strut Channel Production Line Configuration – Punching Methods
The punching process is one of the most important parts of a Strut Channel Production Line. Different punching solutions affect production speed, hole accuracy, tooling cost, and overall automation level. The right Strut Channel Punching System should be selected according to profile thickness, hole pattern, production capacity, and budget.

Speed: Medium to high speed depending on hole pattern and material thickness.
Suitable For: Continuous production of commonly used strut channel profiles.
Advantages: Integrated production process, reduced floor space, and synchronized operation with the roll former.
Solution 4: Post-Punching After Roll Forming (Stop or Flying Punching)
Basic: Holes are punched after the profile is formed using stop punching or tracking punching technology.
Speed: Tracking punching provides higher efficiency for continuous production.
Suitable For: Profiles requiring accurate hole positions after forming.
Advantages: Better dimensional control, especially for complex profiles where forming may affect hole position accuracy.
Solution 5: Roll Punching System

Speed: The fastest punching solution for high-speed production lines.
Suitable For: Large-volume production with fixed hole patterns.
Advantages: No production stopping, continuous operation, and maximum efficiency. Suitable for customers requiring high-speed automatic strut channel manufacturing.
For a professional Uni Strut Channel Roll Forming Machine, the punching method should not only consider speed but also the balance between hole accuracy, tooling cost, production flexibility, and future product requirements. Goalon Machinery can design the suitable punching solution according to your strut channel drawings and production goals.
Strut Channel Production Line Configuration – Cutting Methods
The cutting system is the final processing step in a Strut Channel Roll Forming Machine. It directly affects the finished profile length accuracy, cutting surface quality, and production efficiency. According to different production requirements, strut channel production lines mainly use hydraulic cutting systems or saw cutting systems.
Both cutting methods can be designed as stop cutting or tracking cutting (flying cutting). Stop cutting requires the roll forming line to pause before cutting, while tracking cutting allows the cutter to move together with the profile and complete cutting during continuous production. Tracking cutting provides higher efficiency and is more suitable for automatic high-speed production lines.
Solution 1: Hydraulic Cutting System
Basic: Uses a hydraulic cylinder and cutting die to cut formed strut channels into fixed lengths.
Speed: Medium to high speed, depending on whether stop cutting or tracking cutting is selected.
Suitable For: Standard Uni Strut channels with common thickness and clean cutting requirements.
Advantages: No metal chips, low material waste, and smooth cutting edges. It provides reliable performance and is widely used in strut channel production.
Hydraulic cutting is a popular choice for customers who focus on stable production, simple maintenance, and consistent product appearance.
Solution 2: Saw Cutting System
Basic: Uses a circular saw blade to cut the finished strut channel profile.
Speed: Medium speed, with tracking saw cutting available for continuous production.
Suitable For: Heavy-duty strut channels, thicker materials, and profiles requiring flexible cutting solutions.
Advantages: Strong cutting capability and excellent adaptability for different materials and profile designs.
Saw cutting is especially suitable when the channel thickness is higher or when customers require a universal cutting method for multiple products.
For a professional Strut Channel Production Line, the cutting solution should be selected based on material thickness, production speed, profile requirements, and future product expansion. Goalon Machinery can provide customized hydraulic cutting or saw cutting systems to achieve the best balance between efficiency, accuracy, and investment cost.
Strut Channel Production Line Configuration – Other Design
In a professional Strut Channel Production Line, each process needs to work together smoothly. The punching system and roll forming machine may operate at different speeds. To reduce speed differences and improve production stability, an additional material storage and buffering system can be installed between the punching unit and the roll forming machine.
This design helps control coil movement, reduce tension changes, and maintain continuous production.
Solution 1: Material Storage Rack
A material storage rack is a simple buffering device that stores a certain amount of punched steel strip before it enters the roll forming machine.
Advantages:
- Simple structure and easy installation
- Requires less factory space
- Lower investment cost
- Suitable for standard production requirements
This solution is commonly used when the production speed difference between punching and forming is not large.
Solution 2: Underground Loop Pit
An underground loop pit creates a larger material storage area below the production line. The steel strip forms a loop inside the pit, allowing the punching system and roll forming machine to operate more independently.
Advantages:
- Better speed coordination and production stability
- Reduces material tension during high-speed operation
- Suitable for automatic and high-output strut channel manufacturing lines
However, the underground pit design must consider the customer’s factory conditions, including floor structure, available space, and installation requirements. A safety fence and protection system are also necessary to ensure safe operation around the pit area.
For high-speed Uni Strut Channel Roll Forming Machines, a properly designed buffering system can improve the overall efficiency, reduce downtime, and create a more stable automatic production process. Goalon Machinery can design the most suitable layout based on your production speed, punching method, and workshop conditions.
