Color-Coated Aluminum Coil for Roller Shutter Doors
PPGI.LTD supplies color-coated aluminum coil for roller shutter doors. We slit the coil to fit the slat. We also match the temper to the hooks and curves. The packing protects the narrow coils in transit.
Which Strip Width Fits the Shutter Slat?
The finished slat width is not the strip width. Hooks and curves use extra metal.
| You send | We calculate | We supply |
|---|---|---|
| Slat profile | Developed metal path | Feed width |
| Line drawing | Roll stations and limits | Suitable temper |
| Coil limit | Inner diameter, outer diameter, and weight | Line-ready coil |
Send us the slat drawing. We will calculate the strip width. We will also check the inner diameter and weight.
Can the Surface Handle Daily Rolling?
A shutter flexes every day. The slats may also rub against each other.
| Concern | Check | Buyer benefit |
|---|---|---|
| Bends and hooks | Coating flexibility | Cleaner formed edges |
| Repeated contact | Slat spacing and finish | Less rubbing damage |
| Outdoor exposure | Sun and weather | Suitable resin choice |
We can match the paint to the outdoor use. The door maker must control the slat spacing and line setup. PCI’s forming guide explains why roll condition matters.
How Should Narrow Coils Be Packed?
Narrow coils can move during shipping. They need the right pallet and restraint.
| Packing point | Tell us | We can plan |
|---|---|---|
| Coil orientation | Vertical or horizontal unloading | Pallet layout |
| Surface protection | Visible face and film need | Wrap and separators |
| Identification | Color and slit width | Coil labels and list |
Tell us how you will unload the coils. We will plan the coil direction and pallet layout. TT Club’s coil guide explains why secure restraint matters.
Buyer Concern & FAQ
Can you slit coil to a custom shutter width?
Yes. Send the developed strip width and tolerance.
Which temper is best for the slat?
The hook shape and roll former decide it. Send us the profile first.
Can you add protective film?
Yes, when the film can pass through the line. Confirm the visible side and removal time.
How do you stop narrow coils from moving?
We use suitable pallets and restraint. The plan depends on the coil size and unloading method.
