Zhongtuo Omega Purlin Roll Forming Machine Top Hat & Hat Purlin Machine Approx. 5–7 m/min

The Omega Purlin Roll Forming Machine is a continuous cold roll forming solution for manufacturing omega purlins, top hat sections, hat-shaped channels, and other customized open steel profiles. It is designed for manufacturers working with CR or GI steel who need stable forming, accurate dimensions, and automated punching and cutting.

With multiple forming stations, PLC control, and a servo flying cutoff system, the production line can continuously transform steel coils into finished structural profiles for construction, roofing, solar mounting, modular buildings, and light steel framing.

Continuous Roll Forming for Omega and Top Hat Purlins

The forming section uses 16 forming stations to gradually shape the incoming steel strip. Instead of forming the profile in a single operation, each roller station performs a controlled forming step, helping maintain the required profile geometry throughout production.

The machine supports CR and GI steel with material strength of up to 550 MPa. Standard material thickness ranges from 0.8 to 2.0 mm, while the applicable coil width is approximately 150–300 mm.

The maximum forming speed can reach 20 m/min under suitable production conditions. When punching and cutting are included in the production process, the actual working speed is generally around 5–7 m/min, depending on the profile dimensions, material thickness, hole pattern, and machine configuration.

A servo flying cutoff can cut the formed profile while the production line continues running. This reduces unnecessary stopping and restarting and helps maintain a more consistent production cycle.

Flexible Production for Different Hat Purlin Profiles

One of the main features of this top hat purlin roll forming machine is its ability to be configured for different profile requirements.

Depending on the customer's profile drawing, the machine can manufacture:

• Omega purlins

• Top hat purlins

• Hat sections

• Omega channels

• Customized open steel profiles

• Certain C-shaped structural profiles

The production line can also be equipped with a dedicated punching station. Different punching molds can be selected according to the final application, including single-hole and double-hole punching.

This configuration is useful when the finished purlins need connection holes or mounting openings before they are cut to length.

For solar mounting projects, the same forming principle can be adapted to manufacture customized hat-type solar purlins. Wider profiles, including configurations up to approximately 300 mm, can also be developed according to the required product dimensions.

PLC-Controlled Forming and Automatic Production

Accurate dimensions are important when purlins need to connect with other structural components. The Omega Purlin Roll Forming Machine therefore uses a PLC-based control system to coordinate the forming, punching, and cutting operations.

A 21-inch touchscreen provides an interface for setting and monitoring production parameters. The Windows-based control system also supports CSV file import, which can make it easier to manage different production specifications.

Under suitable operating conditions, the machine can achieve approximately ±1–2 mm dimensional accuracy.

This automated control system is particularly useful for manufacturers producing multiple profile specifications. Instead of repeatedly entering every production parameter manually, operators can manage different settings through the control interface and adjust the production configuration according to the order requirements.

Applications of Top Hat and Omega Purlins

Finished omega and top hat profiles can be used in various lightweight steel construction applications.

Typical applications include roof trusses, wall framing, ceiling systems, partition structures, modular buildings, and lightweight structural frameworks.

Top hat and omega-shaped sections provide a practical combination of lightweight construction and structural rigidity, making them suitable for projects where profile geometry and installation requirements are important.

For solar mounting systems, customized hat purlins can also be manufactured with specific dimensions and connection-hole arrangements. This allows the same roll forming concept to serve both conventional construction and solar structure production.

Customized Omega Purlin Roll Forming Solutions

Different projects often require different profile geometries. For this reason, the machine can be customized according to the customer's profile drawing, steel grade, thickness, coil width, punching pattern, hole position, and required cutting length.

The production line can be configured to include:

• Coil feeding and leveling

• Continuous roll forming

• Automatic punching

• Servo flying cutting

• PLC control

• Customized forming stations

• Different punching patterns

The machine base and forming rollers are designed for continuous production, while the automated control system coordinates the major production operations.

This allows manufacturers to build a production line around their actual product requirements rather than using a single fixed machine configuration.

Omega Purlin Machine Compared with Other Purlin Profiles

Omega and top hat profiles are only part of the structural steel profiles that can be produced with roll forming technology.

For manufacturers requiring other open-section profiles, related equipment can include C purlin, Z purlin, U channel, and L angle roll forming machines.

A C purlin machine produces C-shaped profiles commonly used for wall supports, roof structures, floor beams, and light steel framing.

A Z purlin machine is designed for Z-shaped profiles and can be configured with punching, cutting, and other automatic functions for roofing and large steel structures.

U channel and L angle machines can also be customized for applications such as ceiling frameworks, partitions, structural connections, and finishing components.

The appropriate machine depends on the required profile geometry, material specification, production capacity, and application.
