PolyCor .080 Sides – What Does That Mean?

PolyCor .080 sides are a high-durability composite wall panel used on enclosed trailers instead of traditional thin aluminum. At .080 thickness, these panels are significantly thicker and stronger than standard metal siding, giving you a tougher, longer-lasting trailer. PolyCor panels are dent-resistant, corrosion-proof, and lightweight, making them ideal for customers who want a clean look that holds up to daily use. Unlike aluminum, PolyCor won’t rust, oxidize, or show “wave dents” from road debris or tight loading situations. That’s why the majority of our Yellowstone enclosed trailers come equipped with PolyCor sidewalls as a premium standard feature.
