Decorative Pattern PPGL for Security Doors and Armored Entrance Gates
PPGI.LTD supplies decorative pattern PPGL for security doors with custom designs, thickness, hardness, and back-coat requirements. Choose the visible pattern first. Then match the sheet to the door-forming and filling process.
Which Pattern Fits Your Door Range?
Use a small set of approved patterns to keep the door range easy to produce and sell.
| Design choice | What to confirm | What we can match |
|---|---|---|
| Wood, stone, or abstract look | Artwork or physical sample | Color, repeat, and direction |
| Matt or gloss surface | Target appearance | Approved finish sample |
| Door size and layout | Visible face and trim areas | Pattern position |
We can develop the printed face from an approved design and record it as the production sample.
Will the Sheet Work for Stamping and Deep Drawing?
Deep shapes need a material and paint system that can follow the tool.
| order detail | What to send | Why it matters |
|---|---|---|
| Steel grade and hardness | Required forming range | Controls shape and springback |
| Thickness | Actual ordered value and tolerance | Fits the tool gap |
| Door drawing | Bends, embossing, and draw depth | Checks forming difficulty |
| Protective film | Need and removal timing | Protects the visible face |
Prepainted-metal processing guidance calls for suitable tooling clearance, clean contact points, and protective film. We review the steel, coating, and tool path before confirming the order.
Which Back Coat Fits the Door Filling?
The back face may contact adhesive, foam, honeycomb, or another filling system.
| Filling route | What to confirm | Order requirement |
|---|---|---|
| PU foam | Foam and process temperature | Compatible back coat |
| Honeycomb or board | Adhesive and curing method | Bonding-side finish |
| Welded or framed door | Heat and contact areas | Back-face protection |
Tell us the filling and bonding method. We can match the back coat and surface preparation to the stated production route.
Buyer Concern & FAQ
How can cracking during door stamping be reduced?
Match the steel grade, thickness, paint flexibility, tool radius, lubrication, and draw depth. A forming trial is useful for deeper shapes.
Can I order a custom decorative door pattern?
Yes. Send authorized artwork or a physical sample with colors, repeat, direction, and finish.
Can the back coat be used with PU foam filling?
It can be specified for the planned filling route, but the foam, adhesive, temperature, and process must be confirmed first.
Does the decorative steel skin give the door its security rating?
No. The rating depends on the complete door, frame, lock, reinforcement, fixings, and tested design.
