Double Layer PBR AG Panel Roll Forming Machine for Roof Sheet Production
In the architectural metal cladding industry, production efficiency and equipment investment costs often stand in opposition. Producing two different panel types typically requires purchasing two production lines, occupying double the space, and investing twice the capital. So, is there a single piece of equipment that can meet the production needs of both types of roof panels?
The answer is a definite yes—Double Layer PBR AG Panel Roll Forming Machine for Roof Sheet Production are precisely designed for this purpose.
What is a double-layer roof panel forming machine?
Simply put, the double-layer roof panel forming machine integrates two sets of roll-forming systems with different panel profiles into a single equipment framework, operating independently in upper and lower layers. It enables seamless switching between producing two types of roof or wall panels with different waveforms and purposes without the need to replace rollers or disassemble components.
One host machine, two sets of molds, two types of output—this marks an efficiency revolution over the traditional "one machine, one board" model.

Application scenario: Who needs this device the most?
• Steel Structure Plant Engineering Contractor:
Simultaneously producing roof exterior panels + roof interior panels, or roof panels + wall panels, with on-site switching, one-time layout, and double output.
• Color steel tile processing and leasing:
Mobile construction sites require flexible adaptation to various design drawings, with one machine handling all tasks.
• Medium and small-sized profiled steel sheet processing plants:
Limited workshop space but diverse product requirements make dual-layer equipment the optimal balance.
Overview of Technical Features
• Independent transmission system: The upper and lower layers are equipped with deceleration motors and variable frequency control, which do not interfere with each other.
• Adjustable feed guidance: Suitable for steel coils of different widths, reducing material deviation.
• High rigidity integral frame: annealed after welding to ensure no deformation under long-term heavy load.
• Quick change pressure roller: Some models support quick change of rollers, achieving flexible production of "double-layer+N types of plate".
• PLC+touch screen control: One click call for board type parameters, with fault self diagnosis function.
• Automatic fixed length cutting: equipped with hydraulic cutting device, with an accuracy of ± 1.5mm/10m.

It is not a simple device, but an upgrade of production mode
The double-layer roof panel forming machine does not solve the problem of "whether it can be done", but the problem of "how to do it more efficiently, quickly, and flexibly". If you are worried about the budget for the second production line, or if the workshop can no longer accommodate more equipment, you may want to seriously consider our double-layer equipment. If you need more models, we can also customize them for you.
