The hard plastic decking inside sled trailers is usually called HDPE decking or a plastic bed liner/deck liner , depending on the setup. In trailer and sled-deck discussions, people also commonly refer to it as PVC decking if the boards are fully plastic rather than composite.

Common names

  • HDPE decking : a tough plastic decking material with built-in traction.
  • PVC decking : fully plastic boards, often lighter than composite options.
  • Plastic bed liner / trailer liner : a protective hard plastic sheet or liner screwed over a wood floor.

What people usually mean

If you saw a sled trailer with a hard, grippy plastic surface, the most likely term is HDPE decking. That term shows up in sled-deck brochures and forum posts discussing traction and durability.
