What This Machine Produces
C-slat at 77 mm — the most common shutter profile, with an interlocking hook on both edges. Used on standard commercial shutters.
C-slat heavy at 105 mm — the deeper section gives more stiffness over wide spans and higher wind load.
Z-slat at 77 or 105 mm — the Z geometry gives a more closed appearance with less visible joint, for shutters needing a flatter face.
Perforated slats at 77 mm — an inline perforating unit adds ventilation holes, used on car parks and plant rooms.
Insulated slats at 77 or 105 mm — a foam-filled slat for thermal separation, which needs a separate filling step after forming.
Custom slat depths between 60 mm and 120 mm, though a non-standard depth requires new roll design.
Slats in 0.6–1.2 mm galvanised or pre-painted steel at 15–30 m/min — the highest-speed machine in the range, because the slat section is small and light.
Recommended Configuration
A complete working line, not just the forming machine. Each item below is quoted as one package.
- 01
Decoiler and leveling unit
slats are formed and then interlocked edge to edge, so slat-to-slat fit tolerance decides how smoothly the finished curtain runs in its guides.
- 02
Roller shutter slat machine
12–18 stations on a gearbox chain drive at 5.5–7.5 kW, forming at 15–30 m/min.
- 03
Optional inline perforating unit
punches the ventilation holes during forming, which avoids a separate handling operation and keeps the holes aligned with the slat section.
- 04
Flying cut to length with batch counter
slats are cut to the shutter drop, so a set for one opening comes off together.
- 05
PLC with HMI
slat type, length and batch are selected rather than set by hand.
- 06
A note on coating: use a heavier coating weight than you would on roofing sheet. Shutter slats are handled constantly and abraded every time the curtain rolls into the box, so the coating is a wear surface rather than a finish.
- 07
A note on output: at 20 m/min average the machine produces roughly 800–1,000 m of slat per shift, which is enough for 15–25 typical shutters depending on width and height.
Production Workflow
- 01
Decoiler
Coil is loaded and uncoiled at controlled tension. The slat is a small light section, so tension variation shows as a variation in the interlocking hook rather than as a thickness change.
- 02
Leveling
The strip is straightened before forming. Because slats interlock edge to edge along the whole curtain, a bowed slat produces a curtain that runs out of line in its guides.
- 03
Perforating (optional)
Where ventilated slats are specified, the holes are punched inline while the strip is flat, which keeps the pattern registered to the slat section.
- 04
Roll forming
12–18 stations form the C-slat, Z-slat or insulated slat profile in 0.6–1.2 mm material at 15–30 m/min.
- 05
Cutting
A flying cut cuts to the shutter drop, with a batch counter.
- 06
Assembly (separate step)
Slats are interlocked and held by end caps fitted at each end, then wound onto a barrel. That assembly is a separate operation from this line — the machine produces the slats.

Customization Options
Every line is built to order. These are the points buyers most often change.
| Item | What can be changed |
|---|---|
| Slat type | C-slat, Z-slat, perforated or insulated |
| Slat depth | 77 / 80 / 105 mm standard; custom depths between 60 mm and 120 mm need new roll design |
| Ventilation | Optional inline perforating for car parks and plant rooms |
| Insulation | Foam-filled slat for climate-controlled buildings — the filling is a separate step after forming |
| Material and coating | Commercial quality galvanised or pre-painted steel at 0.6–1.2 mm. Specify a heavier coating weight than for roofing, because slats abrade every time the curtain rolls in |
| Power supply | 380 V / 50 Hz / 3-phase standard; other voltages to your site |
Shutter slat variants and their applications
| Slat type | Depth | Application | Notes |
|---|---|---|---|
| C-slat | 77 mm | Standard commercial shutters | The most common profile; interlocking hook on both edges |
| C-slat heavy | 105 mm | Wide openings, high wind load | Deeper section gives more stiffness over wide spans |
| Z-slat | 77 / 105 mm | Shutters needing a flatter face | Z geometry gives a more closed appearance with less visible joint |
| Perforated | 77 mm | Shutters requiring ventilation | Inline perforating adds airflow — used on car parks and plant rooms |
| Insulated | 77 / 105 mm | Climate-controlled buildings | Foam-filled slat for thermal separation; needs a separate filling step |
