This family forms side guides / U rails, slide rails, shutter boxes (hoods), door tracks, and bottom rails for roller shutters (Chinese 导槽/滑道/罩壳/门轨). English names include U guide, door slide rail, and shutter box forming machine. It is not the curtain-slat main line and not a door-frame machine.
Bottom rails hang here as accessory profiles — do not paste their numbers onto the slat host. Power spans about 7.5 kW to about 75 kW across sections; always select by drawing.
Recommended wording:
Some setups may add weather-strip related processes; details follow the technical proposal.
Applications. Roller-shutter side guides, slides, hood/box sections, thick door rails, and bottom rails. Not interlocking curtain slats; not steel door frames; not garage continuous foaming panels.
| Section | Speed | Main / hydraulic | Stands / shaft | Thickness notes |
|---|---|---|---|---|
| U guide | About 8–12 m/min | About 7.5 / 3 kW | About 14 / φ50 | About 2.0 mm; chain + Delta |
| Slide (flying shear) | About 0–15 m/min | About 18.5 / 7.5 kW | About 26 / φ50 | About 1.5 mm; gear + flying shear |
| Box / hood | About 0–15 m/min | About 7.5 / 3 kW | About 24 / φ76 | About 0.8–1.0 mm |
| Heavy door rail | About 8–15 m/min | Main about 75 kW | Per proposal | About 4–5 mm |
| Item | Documented reference |
|---|---|
| U-guide mass note | About 5.2 t on that U-guide wording |
| Bottom rail | Accessory on this family — not slat main-line parameters |
Ask for the drawing: slat vs guide vs box vs heavy rail. Buyers often use one phrase for several machines.
No. Heavy door rails about 4–5 mm may list main about 75 kW — a different duty class.
As accessory profiles in this guide/box family — not as the curtain-slat main-line parameters.
No. Slide flying-shear packages document higher main/hydraulic power (~18.5/7.5) and more stands (~26).
Final ratings follow the confirmed technical proposal. Price and lead time are out of scope.
