The material that coats the aluminum plates we use to for Plants Map Tags and Signs has been tested by the manufacturer in simulated outdoor conditions and it has been designed to last for more than 10 years.
The black coating has been tested to resist fading from heat exposure, UV and sunlight exposure and a moderate resistance to scratching. Other companies who buy this material include contractor for the military and they use the same material to label the outside of helicopter and airplane parts.
If the QR code on your Plants Map Tag or Sign becomes unreadable we’ll happily replace the tag for free. Just send us back the tag that is not working and we will replace it.
