Production Line
The hat purlin roll forming machine is designed for efficient production of both metal hat purlins and C purlins by changing roller sets. Integrated hydraulic punching, precise roll forming, and flying hydraulic cutting ensure high productivity, dimensional accuracy, and flexible manufacturing for different project requirements.
- Dual-profile production
- Fast roller change
- Consistent punching quality
- Continuous flying cutting
- Reduced production costs
- Flexible profile manufacturing
We customize every hat purlin roll forming machine according to profile drawings, material thickness, punching patterns, production capacity, and future profile expansion requirements.
Ideal for manufacturers producing metal hat purlins and C purlins for steel structures, roofing systems, industrial buildings, warehouses, and commercial construction projects.

Profile Information
Metal hat purlins feature a hat-shaped cross section that provides excellent stiffness while reducing structural weight. They are widely used in roofing systems, wall framing, ceilings, and secondary steel structures.
Commonly manufactured from galvanized steel or cold-rolled steel with thicknesses of 1.5–3.0 mm, they are popular across the Middle East, Southeast Asia, Africa, and Latin America, and are efficiently produced using a roll forming machine.
How Does The Roll Forming Machine Work?
Machine Details
Hydraulic decoiler+Leveler
The integrated decoiler and leveler continuously unwind and flatten steel coils before forming. Proper leveling removes coil stress, improving feeding stability, punching accuracy, and final profile consistency.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Punching Unit+Servo Feeder
The servo feeder accurately positions the strip according to programmed lengths before each punching cycle.
Combined with the hydraulic punching machine, it delivers fast, repeatable hole patterns with excellent positional accuracy. This system significantly improves assembly precision while maintaining reliable performance for continuous production.
Roll Forming Machine
The hat purlin roll forming machine uses a wall-panel structure with a durable chain driving system to gradually form steel into precise profiles.
By replacing roller sets, the same machine efficiently produces both metal hat purlins and C purlins, reducing equipment investment while maximizing production flexibility.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Flying Hydraulic Cutting Unit
The flying hydraulic cutting system synchronizes its movement with the continuously moving profile during cutting. Since the cutting unit travels at the same speed as the roll forming machine, production never stops, ensuring clean cuts, high efficiency, and consistent finished lengths.
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
No. The flying hydraulic punching system operates synchronously with the moving profile, allowing continuous production without interrupting roll forming.
Yes. Punching dies are designed according to your profile drawings, including service holes, installation holes, and special customer requirements.
The servo feeder positions the steel strip with high accuracy before each punching cycle, ensuring consistent hole spacing and precise alignment with the finished hat purlin profile.
No. The flying hydraulic cutting system travels with the profile, allowing continuous production without stopping the roll forming machine.
With precision roll forming, synchronized flying punching, and hydraulic cutting, the machine produces consistent profile dimensions and repeatable hole positions.
There is no need to worry. Our machines are designed for easy installation and operation.
Before shipment, we will finish the main assembly and testing in our factory. When the machine arrives, you only need to place it in position, connect the power supply, and it can start working.
We will also provide:
detailed installation and operation manuals
machine layout drawings
wiring diagrams
online technical support (video call / photos / videos)
If needed, we can also arrange an engineer to come to your factory to help with installation and training. Many of our customers complete installation smoothly with our online guidance.
