Against The Alternatives
| Plain galvanized sheet painted on site | Factory colour coating is cured to the coil and is dramatically more uniform and durable than site-applied paint. |
|---|---|
| Aluminium sheet | Aluminium resists corrosion better but costs more and has lower stiffness, so prepainted steel remains the default for large roof areas. |
| Buying coil and sheet from different sources | Trial sheet and production coil from one source keeps the colour consistent across the finished roof. |
Getting It Right On Site
- Confirm substrate, coating weight, thickness and width on the order
- Store coil dry and off the ground, on its packing
- Handle with coil clamps or a mandrel, never by the edge
- Remove protective film within the period stated for the film
- Use fixings and sealants compatible with the coating
Customisation Options
- Packaging, carton marking and labelling to your requirement
- Private label and colour box packing on agreed quantities
- Quantity per carton adjusted to suit your handling and shelf layout
- Mixed item loading so several product lines share one container
