RhinoPoly® is our proprietary blend of thermoplastics, pigments, and UV stabilizers. So what does that all mean? Well in our TriView® marker post it means you can run it over many times and it still gets right back up looking good. That’s because of it’s durability and flexibility. In the baking sun in a desert our products remain temperature stable and can withstand the elements. We believe so much in our RhinoPoly® that we back the products made of it with a 10-year warranty.
