The ramp core is fully protected by a tough polyurea coating that helps resist abrasion, chemicals, UV exposure, moisture, and everyday trailer abuse. The micro-textured surface adds grip where it matters most, helping the tire and trailer interface stay more controlled during loading and unloading. Because the construction is non-marring and corrosion-free, these ramps will not rust, soak up water, or scratch coated floors the way metal edges can. Sold as a matched pair, the APEX 36-inch trailer ramp kit gives both tracks the same approach profile for more consistent, confident loading.
