Corrugated Iron Sheet Roll Forming Machine
762 / 900 / 1000 mm corrugated iron roofing sheet at up to 30 m/min. The highest-throughput profile in the roofing range because the wave geometry is simple.

What This Machine Produces
762 mm corrugated iron sheet — 12 full waves across the sheet, the traditional specification in the UK, Ireland, Australia and much of Africa.
900 mm corrugated sheet — 14 waves, common in Southeast Asia and the Middle East because it uses coil more efficiently than 762 mm.
1000 mm corrugated sheet — 16 waves, the lowest sheet cost per square metre where wider coil stock is available.
A consistent wave pitch of 32 mm with wave height of 17–19 mm, so sheets from different production runs still nest and lap correctly.
Sheets in 0.3–0.8 mm galvanised, pre-painted or colour-coated steel at 20–30 m/min — the highest throughput in the roofing range, because the wave geometry is the simplest we form.
Trapezoidal profile as well, if you order an additional roll cassette: corrugated and trapezoidal are different wave geometries, so the tooling is not shared, but the base frame, decoiler, cutting unit and control system are common.
Recommended Configuration
A complete working line, not just the forming machine. Each item below is quoted as one package.
- 01
3-tonne hydraulic decoiler
included as standard. 5 T and 10 T decoilers are available where you buy coil in heavier weights.
- 02
7-roller leveling unit
included as standard. Corrugated is a shallow, wide wave, so any coil set shows across the full sheet width rather than being hidden by the profile.
- 03
Corrugated sheet roll forming machine
12–16 stations on a gearbox chain drive at 7.5–11 kW, forming 0.3–0.8 mm at 20–30 m/min.
- 04
Hydraulic flying cut
for a roofing producer running long batches of the same sheet, stopping the line at every cut is what kills throughput.
- 05
PLC with encoder-based length control
the encoder counts coil feed and triggers the shear at the programmed length, so sheets are cut to length and counted in batches automatically.
- 06
Runout table
762 mm corrugated is stiff and awkward; a supported runout keeps the sheet flat and stops it marking the next one.
Production Workflow
- 01
Decoiler
Coil is loaded on the 3 T hydraulic decoiler and uncoiled at controlled tension. Corrugated runs at 20–30 m/min, so the decoiler has to keep up without inducing tension variation along the sheet.
- 02
Leveling
A 7-roller leveling unit removes coil set from the 0.3–0.8 mm strip before forming. Because corrugated is a wide shallow wave, residual bow appears as a twist across the sheet rather than in the profile.
- 03
Roll forming
12–16 stations form the 32 mm pitch wave. The station count is low because the wave geometry is simple — this is the reason the line runs faster than any other profile we build.
- 04
Speed management
At 0.3–0.5 mm with correctly set die clearance the line runs at up to 30 m/min. For 0.6–0.8 mm we recommend 20–22 m/min so that profile geometry stays consistent and the coating is not marked.
- 05
Cutting
The hydraulic flying cut is triggered by the PLC encoder at the programmed length, with a batch counter.
- 06
Output
Finished sheets leave on the runout table, already counted in batches.

Customization Options
Every line is built to order. These are the points buyers most often change.
| Item | What can be changed |
|---|---|
| Effective width | 762 mm (12 waves), 900 mm (14 waves) or 1000 mm (16 waves) — each needs its own tooling on the same base frame |
| Additional profiles | Trapezoidal cassette available for the same frame |
| Optimised widths | In 762 mm form the line can be set to 760, 810, 820 or 828 mm effective width |
| Material | Galvanised, pre-painted or colour-coated steel |
| Thickness | 0.3–0.8 mm — the 30 m/min figure applies to 0.3–0.5 mm |
| Decoiler capacity | 3 T standard, or 5 T / 10 T for heavier coil |
| Power supply | 380 V / 50 Hz / 3-phase standard; other voltages to your site |
Corrugated sheet widths and where each is used
| Effective width | Wave count | Main markets | Notes |
|---|---|---|---|
| 762 mm | 12 full waves | UK, Ireland, Australia, West & East Africa | The classic corrugated iron specification; heaviest fixing density |
| 900 mm | 14 waves | Southeast Asia, Middle East | Better material utilisation, common where 900 coil is cheaper |
| 1000 mm | 16 waves | Middle East, North Africa, Latin America | Lowest sheet cost per m², requires wider coil stock |
