The Eaves Struts Channel Roll Forming Machine is a specialized cold roll forming solution for producing eaves struts, eaves beams, gutter support profiles, and related structural sections from galvanized or pre-painted steel coils. In modern steel building construction, these profiles help support roof edges, gutters, top sheeting rails, and other roofing components while maintaining a stable and reliable structural connection.
To meet different production requirements, ZT has developed a flexible roll forming system that can manufacture not only Eaves Struts Channels, but also C Purlins, Z Purlins, and Sigma Eaves Beams with suitable tooling and adjustment configurations. As a result, one production line can cover multiple structural profiles, helping manufacturers reduce equipment investment and improve machine utilization.
Eaves Struts Channel and Sigma Eaves Beam Production
An eaves strut, sometimes called an eaves beam purlin, normally serves as a structural member around the eaves of a steel building. It can support roof sheeting, gutters, and associated components while transferring loads to the main structural framework.
Meanwhile, the Sigma Eaves Beam has become another practical profile for modern steel construction. Its section design provides an alternative solution for specific structural applications. Because both profiles can be produced through cold roll forming, manufacturers can use a properly configured machine to expand their product range without purchasing a completely separate production line.
More importantly, we can configure the forming system according to the required profile dimensions, steel thickness, punching pattern, and production capacity. This approach gives customers greater flexibility when they need to manufacture several structural sections on one machine.
One Machine for C, Z, Eaves Strut and Sigma Profiles
Many steel fabrication companies need different purlin and eaves profiles for different projects. Traditionally, producing each section may require a dedicated machine, additional workshop space, and higher investment. Therefore, we developed a multi-profile solution based on the principle of “one machine, multiple applications.”
With suitable roll tooling and an automatic adjustment system, the equipment can be configured to produce C purlins, Z purlins, Eaves Struts Channels, and Sigma Eaves Beams. The machine can also integrate feeding, leveling, punching, roll forming, and cutting into one continuous production process.
Furthermore, the PLC and industrial computer allow operators to enter production parameters such as profile dimensions, hole positions, cutting length, and batch quantity. Once the settings are confirmed, the system coordinates the production sequence automatically, reducing unnecessary manual intervention.
This configuration is particularly useful for manufacturers who want to save investment, reduce floor-space requirements, and increase product diversity.
Heavy-Duty Structure and High-Precision Roll Forming
To maintain stable forming performance when processing steel strips around 1.5–3.0 mm thick, the machine uses a rigid welded steel frame and high-quality forming components. The forming rolls can be manufactured from GCr15/GCr12MoV hardened steel, while the solid shaft uses high-grade steel to provide sufficient strength during continuous operation.
In addition, the machine can use precision linear guide components and a carefully designed guiding system to keep the strip aligned throughout the forming process. The leveling section helps flatten the incoming material before it enters the punching and forming stages. Consequently, the finished eaves strut or purlin maintains a consistent profile and better dimensional accuracy.
For applications requiring frequent profile changes, an automatic adjustment configuration can further reduce setup time. Instead of repeatedly making extensive manual adjustments, operators can select the required dimensions through the control interface, depending on the machine configuration.

The actual output speed depends on the profile geometry, steel thickness, hole pattern, cutting method, and required dimensional accuracy. For this reason, we recommend confirming the final profile drawing before selecting the motor, forming stations, and production speed.
Automated Punching, Cutting and Control System
The Eaves Struts Channel Roll Forming Machine can integrate hydraulic punching and automatic cutting directly into the production line. This means the operator does not need to process every finished section separately after forming.
Before production begins, the operator can input the required length, quantity, and punching parameters through the PLC control system. The machine then feeds the coil, levels the material, performs the programmed punching operation, forms the profile, and cuts it to the required length.
At the same time, the control system can store production data for frequently manufactured specifications. This feature makes repeat orders easier to manage and helps reduce setup errors.
For customers with different electrical standards or language requirements, we can also customize the electrical components, PLC brand, control language, voltage, and other configuration details.
Applications, Quality Control and Global Support
Eaves struts and eaves beams are widely used in steel warehouses, workshops, factories, agricultural buildings, commercial structures, roofing systems, and other metal building projects. Their applications can include eaves support, gutter support, top sheeting rails, and other structural connections.
Before shipment, we test the complete forming line to verify the feeding, leveling, punching, forming, cutting, electrical control, and safety functions. We also provide machine videos and test reports when required, allowing customers to review production performance before delivery.
After installation, our technical team can provide remote assistance for commissioning, operation, maintenance, and troubleshooting. For overseas projects requiring additional support, engineer service can also be arranged according to the project requirements.
Most importantly, we do not simply supply a standard machine. We can study your C/Z purlin, eaves strut, or Sigma eaves beam profile drawing and recommend the appropriate roller configuration, punching system, cutting method, motor capacity, and automatic adjustment solution.
