Profile Information
IBR and corrugated roof panels are used for roofing and cladding; IBR features trapezoidal ribs, corrugated has wave patterns, widely used in Africa, Southeast Asia, and South America.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Roll Forming Machine
The double layer roll forming machine adopts a wall panel frame and chain driving system, ensuring stable forming and long service life.
Its dual-layer structure allows IBR production on the upper layer and corrugated panels below, maximizing efficiency without increasing footprint. Manual or automatic switching options are available.

| 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 |
Cutting Unit
The double layer hydraulic cutting system performs precise post-forming cutting for both IBR and corrugated panels, ensuring clean edges without deformation.
It operates through hydraulic power with synchronized control, matching forming speed. Optional encoder tracking improves accuracy, while basic systems use fixed-length cutting.
| Power Type | Hydraulic cut |
| Power | 5.5Kw |
| Blade Material | Cr12MoV |
| When Cutting | Forming stops |
| Length Tolerance | ≤±1mm |
Convyor
After cutting, IBR roof panels can be collected by an out table or an auto stacker, depending on production requirements.
| Item | Out Table | Auto Stacker |
| Type | Manual / Semi-manual | Fully automatic |
| Investment | Low cost | Higher initial investment |
| Labor | Requires manual handling | Reduces labor significantly |
| Efficiency | Suitable for low–medium speed | Ideal for high-speed production |
| Flexibility | High | Moderate |
| Stacking | Manual, less consistent | Automatic, neat and consistent |
| Maintenance | Simple | More complex |
| Application | Small to medium production lines | Large-scale, continuous production |
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.
Optional Upgrade —— Flim Laminator
- Protects the panel surface from scratches during forming, cutting and stacking
- Improves finished panel appearance, especially for pre-painted and high-end roofing sheets
- Reduces rejection and rework caused by surface damage
- Provides extra protection during handling, packing and transportation
- Increases product value for premium roofing projects
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, each layer operates independently with stable speed, ensuring efficient production comparable to single-layer machines. The standard configuration operates at 15–20 m/min. Higher-end configurations can reach 30–40 m/min, and even higher speeds can be customized according to specific production requirements.
Lead times range from 30-50 days post-order, varying by customization level and supplier location. We typically require 45 days for standard machines.
Yes. After communicating with you about your requirements, we can first provide a quotation and a similar solution based on a profile that is close to your needs for your reference. Once the exact drawing becomes available, we can update the quotation and configuration accordingly at any time.
Yes. We are a professional manufacturer that produces both standard market profiles and customized profiles. We can also sign an agreement to ensure that your drawing will not be shared with other parties.
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.
Switching is done by selecting the working layer, typically through control system operation, with minimal setup time and no complex mechanical adjustments.
