and slitting; trimming
FORSTNER Multiple Decoiling Lines at FläktGroup in Germany. Discover how roofers are improving their productivity through coil handling and slitting and cutting to length, and taking their processes to the next level.
Roofing companies that excel have one thing in common: they quickly and accurately transform material into finished profiles, without delays. That’s why more and more manufacturers are moving the process closer to the coil. Modern coil-handling and slit-and-cut, or Cut-to-length (CTL) lines turn thin sheet coils directly into ready-to-use blanks with high precision. The result: less waste, shorter lead times Roofing companies that excel have one thing in common: they bring their production processes in-house and invest in modern coil-handling and slit-and-cut-to-length (CTL) lines. With these systems, thin sheet coils are rapidly converted into precision-cut sheets, fully tailored to current demand. The result: less waste, shorter lead times, and production free of unexpected bottlenecks. and no bottlenecks.
From Supply Risks to a Stable Material Flow
Anyone who relies on pre-cut sheets is at the mercy of suppliers’ schedules and capacity. By producing from coil yourself, that changes completely. You work with a smaller number of coil types and thicknesses and then cut them exactly to size whenever you need them.
The material enters the system once and then flows entirely through your own process. That means:
- fewer handling steps
- less shipping and receiving
- less chance of damage such as dents or scratches
This gives you added flexibility. If there’s a rush order or a product dimension changes, you can simply adjust the settings and continue production right away. This prevents downtime both on the factory floor and at the construction site.
Precision from the Source
The precision achieved early in the process carries through to the final product. Modern slit and Cut-to-length lines use servo-controlled feeding, encoder feedback, and integrated alignment technology that corrects coil distortion even before the first cut.
The result:
- constant widths
- right angles
- lengths within very tight tolerances
On a FORSTNER nuSLIT , finished panels are produced at speeds of up to 25 meters per minute—ready for the next processing step.
That precision pays off at every stage of your process: cleaner cuts, less post-processing, and bending programs that don’t need to be reset over and over again. This reduces scrap costs and increases material yield.
Safer and Easier Material Handling
A modern coil line replaces physically demanding and risky lifting work with controlled, safe movements. For example:
- powered Coil cars
- extendable tensioning pins
- automatic loop check
- smart decoiler stations
- Integrated security and locking system
Straighteners ensure perfect feeding, resulting in tight and precise feeding.

The effect?
Fewer injuries, a calmer work environment, and operators who can focus on quality rather than heavy lifting. The training period for new employees is also significantly shorter.
Made for the pace of roofing companies
Many workshops produce in small batches, with frequent product changes and tight deadlines. Modern production lines are perfectly designed for this:
- programmable slitting
- recipe libraries
- automatic length settings
- link to order data
In many cases, an operator simply needs to scan a work order, after which the correct settings are loaded automatically. This boosts efficiency and reduces errors at the same time.
Less stock, more grip
Coils take up less space than stacks of pre-cut sheets. With the right planning, you can:
- reduce the number of SKUs
- Keep less sheet material in stock
- offer a wider selection after all
This offers a huge advantage, especially when project details change at the last minute or the supply chain is unstable. You own the coil—so you control the end result.
