Distinguished Properties
1. Aluwedo mass finish aluminum composite panel reaches a 25% less of finish comparing with others
2. This kind of Aluminum composite panel is applicable in screen printing and direct-to-substrate digital printing
3. The ACP is of smooth and flat surface; printed film will help to extend the panels' service life
4. The panel surface can be coated to be brightened and attractive
5. Featuring outstanding weather resistance
6. The ACP comes with at least 5 years guarantee in outdoor applications
7. UV protection
8. It can be routed and returned to add dimension or roll-formed to deliver sweeping curves
9.PE colours come with a 5 year external guarantee.
10. Exceptionally rigid against comparable traditional sign materials; shown is a comparison table of 4 kinds of panels:
