Output

What This Machine Produces

01

C-slat at 77 mm — the most common shutter profile, with an interlocking hook on both edges. Used on standard commercial shutters.

02

C-slat heavy at 105 mm — the deeper section gives more stiffness over wide spans and higher wind load.

03

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.

04

Perforated slats at 77 mm — an inline perforating unit adds ventilation holes, used on car parks and plant rooms.

05

Insulated slats at 77 or 105 mm — a foam-filled slat for thermal separation, which needs a separate filling step after forming.

06

Custom slat depths between 60 mm and 120 mm, though a non-standard depth requires new roll design.

07

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.

Line Composition

Recommended Configuration

A complete working line, not just the forming machine. Each item below is quoted as one package.

  1. 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.

  2. 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.

  3. 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.

  4. 04

    Flying cut to length with batch counter

    slats are cut to the shutter drop, so a set for one opening comes off together.

  5. 05

    PLC with HMI

    slat type, length and batch are selected rather than set by hand.

  6. 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.

  7. 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.

How It Runs

Production Workflow

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 05

    Cutting

    A flying cut cuts to the shutter drop, with a batch counter.

  6. 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.

Common Questions

FAQ — Roller Shutter Door Roll Forming Machine

What slat sizes are standard?
77 mm and 105 mm slat depths are the most widely used global sizes. We also build 80 mm and any custom depth between 60 mm and 120 mm, though a non-standard depth requires new roll design.
Can the machine produce perforated ventilation slats?
Yes. An optional inline perforating unit punches ventilation holes during forming, which avoids a separate operation and keeps the holes aligned with the slat section.
What is the difference between a shutter slat machine and a door frame machine?
A shutter slat machine forms the interlocking slat profiles that roll up into a shutter curtain. A door frame machine forms the structural frame profiles — L, U or Z sections — that hold the door leaf and are fixed into the wall opening. They are different products serving different parts of the same building.
What steel grade and coating are used for shutter slats?
Commercial quality GI or PPGI at 0.6–1.2 mm. Coating weights are usually higher than on roofing, because shutters are handled constantly and are exposed to abrasion from the curtain rolling into the box.
How is the curtain assembled from the slats?
Slats interlock edge to edge and are held by end caps fitted at each end. The assembled curtain is then wound onto a barrel, so slat-to-slat fit tolerance directly determines how smoothly the shutter runs.
What output is typical?
At 20 m/min average, a slat machine produces roughly 800–1,000 m of slat per shift, which is enough for 15–25 typical shutters depending on width and height.
Can the machine be built for our own profile?
Yes. Send the profile drawing with the section dimensions, the material and thickness, and the coil width you intend to run. We confirm the roll design, forming stations and line layout against that drawing before quoting, so the machine matches the section you actually sell.
How do we get a price for this line?
Send the profile drawing or section dimensions, the material and thickness, the coil width, and your target output per shift. Price depends on the profile, the coil and the level of automation, so we quote against your actual job rather than a catalogue figure.
What material thickness can this machine form?
Material thickness runs 0.6 – 1.2 mm. The roll gap, drive and cutting unit are set for this range, so staying inside it is what keeps the section geometry repeatable run after run.
What is the production speed?
Forming speed is 15 – 30 m/min. Treat this as the line speed: real shift output also depends on cut length, coil reloading and how often the profile is changed.
How many forming stations does it use?
The line uses 12 – 18 forming stations. Station count follows the section — more bends and tighter tolerances need more forming steps, which is why two profiles rarely share one roll set.
What is the drive and installed power?
Drive: Gearbox chain drive, 5.5 – 7.5 kW. Final drive sizing is confirmed against your profile and coil, because a wider or thicker section needs more torque to hold the same line speed.
