Standard Double-Layer Roof Line vs High-Speed 40 m/min Class

1. Scope
Double-layer roof lines put two roll sets (upper / lower) on one frame so a plant can produce two profiles without two complete hosts. This page compares two different configurations of that idea: a standard-speed English-quote class and a high-speed about 30–40 m/min class. Do not merge their numbers into one invented machine.
2. What both share
- Upper and lower profile stacks on one frame
- Typically one active layer at a time (shared drive / hydraulics)
- Coil → guide → form → cut → exit process pattern
3. Side-by-side comparison
| Point | Standard class | High-speed ~40 m/min class |
|---|---|---|
| Speed | About 0–20 m/min | About 30–40 m/min |
| Forming / main power | About 5.5 kW | 18.5 kW forming motor |
| Stations | Upper ~17 / lower ~24 | Upper 16 / lower 17 |
| Shaft | φ70 mm | φ85 mm |
| Cut | Hydraulic cut (~5.5 kW cut motor; ~4.5 kW pump station) | Servo tracking cut ~11 kW; hydraulic station ~11 kW + accumulator |
| Material language | Corrugated ~0.12–0.3 mm; trapezoid ~0.3–0.55 mm; feed 1000 mm | ~0.3–0.5 mm high-strength G550 |
| Decoiler / exit (typical) | ~5 t class; simple collect table options | ~10 t hydraulic uncoiler → ~12 m auto stack flow |
4. Standard class detail
Oriented to corrugated + trapezoidal dual production with chain drive and Delta-class PLC on common packages. Good fit when output demand sits in the low-to-mid teens m/min class and thickness bands differ by layer.
5. High-speed class detail
Heavier forming power, larger shaft, fewer but faster-oriented stations, and servo tracking cut for continuous high throughput. Material statement is a single G550 thickness band — not the dual corrugated/trapezoid bands of the standard class.
6. How to choose
- Required output class (m/min or sheets/shift)
- Material grade / thickness strategy (dual bands vs G550)
- Cut quality / tolerance needs (hydraulic stop-cut vs tracking)
- Floor space for 10 t decoiler + long auto stacker
- Budget for 18.5 kW-class forming vs 5.5 kW-class
Glazed-tile single-layer codes are outside this comparison.
7. Buyer FAQ
Can I advertise both 20 and 40 m/min on one machine?
No. Those are different configurations.
Are station counts higher on the high-speed line?
Not in this pairing — standard shows 17/24; high-speed shows 16/17. Power and cut mode change more than stand count.
Where is the family overview?
See the double-layer roof panel encyclopedia overview entry for shared concepts.
Final ratings follow the confirmed proposal for the selected class. Price and lead time are out of scope.
