PPGI Coils for Pre-Engineered Buildings: What Should You Order?
To order PPGI coils for pre-engineered buildings, send PPGI.LTD your panel drawing, size, color, and project rule. We will check the coil details before we quote.

Start with the panel you will make. Roof, wall, and sandwich panels need different coil details.

|---|---|---|
| Roof panel | Weather and panel shape | Drawing, thickness, coating, paint, and width |
| Wall panel | Color and smooth forming | Drawing, thickness, color, paint, and width |
| Sandwich panel | Flat face and bonding | Face thickness, front paint, back side, and width |

Coil Colors and Paint TypesCheck the Width, Shape, and Color
Check the width
Send the drawing and the width that enters your machine.
Check the shape
Tell us if you will bend or roll the coil.
Check the color
Send the color code and tell us which panels sit side by side.
Our coil width guide explains why the width that enters the machine can differ from the finished panel width.
The project engineer chooses the building loads. We supply the coil to the agreed steel details.
Buyer Concern & FAQ
What should I send for a PEB coil quote?
Send the panel use, drawing, project rule, steel thickness, coating, paint, width, coil weight, and color.
Does every roof panel need G550 steel?
No. The right steel depends on the project rule and the panel shape. G550 is only one choice.
Should I use PPGI or PPGL?
It depends on the project rule, weather, coating, and panel use. Send us these details so we can compare the two.
How do I choose PE, SMP, or PVDF paint?
Follow the project rule, weather needs, color needs, and budget. We check the paint with the full coil order.
Can roof, wall, and sandwich panels use the same coil?
Sometimes. The steel, thickness, coating, paint, width, and forming work must all match.
