A Hat Purlin Roll Forming Machine is designed to continuously produce hat-shaped steel profiles from metal coils. Hat sections, also known as hat purlin, hat profiles, or hat-shaped steel sections, are widely used in building support systems, wall structures, roofing frameworks, equipment frames, industrial supports, and other light steel applications.
Unlike a conventional fixed-size roll former, this machine features an adjustable profile height design. It allows manufacturers to produce hat sections with different web heights within a specified range without installing a completely separate production line for every size.
The machine shown here is designed mainly for galvanized steel from 0.8 to 2.0 mm thick. The finished profile height can be adjusted from approximately 50 to 110 mm, while the production speed can reach up to 28 meters per minute, depending on the material, punching pattern, profile dimensions, and actual operating conditions.
The complete line combines roll forming, hydraulic punching, hydraulic cutting, PLC control, profile size adjustment, and finished-product receiving into one continuous production process.
Why Use an Adjustable Hat Purlin Roll Forming Machine?
Many traditional Hat Purlin Roll Forming Machines are built around one fixed cross-section.
This solution works well when a factory produces the same profile continuously. However, manufacturers serving different construction projects or OEM customers often receive orders with different hat section heights.
For example, one project may require a relatively low hat profile, while another may require a taller section for a different support structure.
Purchasing a separate machine for every profile height can increase equipment investment, occupy more factory space, and make production planning less flexible.
The height-adjustable design of this machine provides another option.
The forming system includes a dedicated adjustment mechanism that changes the relevant forming position according to the required profile specification. For this machine, the hat section height can be adjusted within approximately 50–110 mm.
This makes the line particularly suitable for manufacturers handling multiple hat profile sizes and changing project orders.
An Adjustable Hat Purlin Roll Forming Machine is therefore not only about production speed. Its main advantage is the ability to expand the number of profile specifications that can be covered by one production line.
Hat Section Profile Shape and Finished Product
The finished product has a typical hat-shaped cross-section.
The center section rises above the two side flanges, while the edges include small lips that contribute to the final shape and rigidity of the profile.
For the machine shown here, the reference profile dimensions are:
| Profile Item | Reference Specification |
|---|---|
| Product | Hat Section / Hat Channel |
| Top Web | 40 mm |
| Profile Height | 50–110 mm adjustable |
| Flange | 26 mm |
| Lip | 10 mm |
| Main Side Angle | Approx. 75° |
| Lip Angle | Approx. 45° |
| Material | Galvanized Steel |
| Material Thickness | 0.8–2.0 mm |
Hat profiles are not limited to one standard dimension.
For a new project, the forming rollers, punching system, size adjustment range, and cutting design can be developed according to the customer’s actual profile drawing.
For this reason, a Hat Purlin Roll Forming Machine should normally be selected according to the final product rather than only by comparing general machine specifications.
Heavy-Duty Forming Shafts Support Stable Production
One of the most noticeable details in the machine photos is the robust forming shaft structure.
In roll forming equipment, customers often focus first on machine speed, motor power, or PLC brand. However, the mechanical structure of the forming section is equally important.
The forming rollers are mounted on shafts, and these shafts continuously carry forming loads while the steel strip passes through each forming station.
When thicker material is used, the forming resistance increases.
A stronger shaft structure helps the rollers maintain a stable working position during continuous production, especially when processing galvanized steel within the 0.8–2.0 mm thickness range.
The machine also uses solid mechanical support around the shaft and roller area.
This type of structure is important because the quality of a finished hat section depends not only on the roller profile itself, but also on several connected factors:
- shaft rigidity;
- roller machining accuracy;
- bearing support;
- machine frame strength;
- roller alignment;
- forming sequence.
When comparing different Hat Purlin Making Machines, looking at the actual forming structure can provide more useful information than comparing production speed alone.
Multi-Stage Roll Forming for a Stable Hat Profile
A hat-shaped steel profile is not normally formed in one single operation.
After the metal strip enters the main forming machine, it passes through a series of roller stations. Each station gradually changes part of the strip until the final Hat Section geometry is produced.
This progressive forming method helps control material deformation.
For a profile containing a top web, inclined side walls, bottom flanges, and edge lips, the sequence of each forming step needs to be carefully arranged.
The forming process becomes even more important on an adjustable machine.
A Height Adjustable Hat Purlin Roll Forming Machine must not only create the correct final shape, but also maintain the required forming relationship when the profile height changes.
Therefore, an adjustable Hat Section machine is more than a standard roll former with an additional adjustment button.
The forming rollers, shafts, mechanical adjustment system and profile design must work together as one system.
Integrated Hydraulic Punching for Hat Purlin with Holes
Many Hat Sections used in construction or industrial assemblies require mounting holes or connection holes.
One production method is to form the complete profile first and then move it to another punching machine. However, this creates an additional process involving transportation, repositioning, and secondary handling.
This machine integrates a Hydraulic Punching Station directly into the production line.
The actual machine images show multiple hydraulic cylinders, hydraulic connections, and punching components installed within the equipment.
The punching system can be designed according to the customer’s profile requirements, including hole shape, hole position, spacing, and production sequence.
After punching, the material continues through the subsequent production stages.
Integrating punching into the Hat Purlin Roll Forming Line reduces the need for separate post-processing and makes the overall workflow more efficient.
For manufacturers producing profiles with repeated mounting holes, a Hat Purlin Roll Forming Machine with Hydraulic Punching can be particularly useful.
Counting and Position Detection for Continuous Production
Automatic profile production requires accurate control of material movement.
The machine must coordinate several operations, including punching position, profile length, cutting position, and production quantity.
The equipment includes a counting and position-detection mechanism that supports this process.
Combined with the PLC control system, this type of detection structure helps coordinate the different operations of the production line.
For batch orders involving a large number of profiles with the same specifications, automatic counting and length control can reduce repeated manual measurement and simplify production management.
PLC Control for Different Production Orders
The line is equipped with a PLC control system for automatic operation.
Depending on the final configuration, the operator can set production information such as finished length and required quantity through the control interface.
The machine then coordinates the corresponding production actions.
When another order requires a different product length, the operator can update the production parameters instead of manually measuring every finished section.
For orders requiring a different Hat Section height, the size adjustment system can be used together with the mechanical forming structure.
This combination makes the machine suitable for factories producing multiple batches and multiple Hat Channel specifications.
Production Process from Steel Coil to Finished Hat Section
A typical production process for this machine is:
Steel Coil → Feeding and Guiding → Hydraulic Punching → Roll Forming → Length Cutting → Finished Profile Receiving
The main units of the production line include:
| Machine Unit | Main Function |
|---|---|
| 4T Decoiler | Supports and releases the steel coil |
| Feeding / Guiding Unit | Guides the strip into the production line |
| Hydraulic Punching Station | Produces required holes |
| Roll Forming Machine | Forms the Hat Section continuously |
| Size Adjustment System | Adjusts the profile height |
| Hydraulic Cutting | Cuts the finished section to length |
| PLC Control System | Controls production parameters |
| Receiving Table | Supports finished profiles after cutting |
This integrated production arrangement helps reduce intermediate handling between different processing stages.

Who Can Benefit from an Adjustable Hat Purlin Machine?
A fixed-size roll forming machine is often sufficient for a factory producing only one profile specification.
An adjustable machine becomes more useful when production requirements change frequently.
Typical users include:
- building profile manufacturers;
- light steel component factories;
- OEM metal profile suppliers;
- steel structure manufacturers;
- industrial component producers;
- factories serving different construction projects.
The machine is particularly suitable when the manufacturer needs to produce several Hat Section heights while maintaining the same general profile family.
Combining size adjustment with online punching also helps reduce the number of separate production processes.
What Information Is Needed Before Designing a Hat Purlin Machine?
A Hat Section Roll Forming Machine is normally designed around the final product.
Before confirming the machine configuration, it is useful to provide an accurate profile drawing showing the complete section dimensions.
Other important information includes:
- raw material type;
- steel thickness range;
- finished profile length;
- required adjustable height range;
- punching requirement;
- hole diameter or hole shape;
- hole spacing;
- required production speed;
- factory power supply.
If online punching is required, the hole pattern should be confirmed as early as possible because punching position and production sequence can influence the overall machine design.
If a formal CAD drawing is not yet available, a clear finished-product photo with complete dimensions can also be used for preliminary technical evaluation.
