Plastic pallets are used for more than just industrial shipping applications. Sometimes they are also considered for fun (and a little protection from flying paint).
Paintball ranges offer lots of hiding spots and shelters. We once had an inquiry for the cheapest plastic pallets offered by Nelson Company to use as bunkers.The paintball range had tried wood pallets. Unfortunately, the wood pallets have too much space between boards and players taking cover were getting splashed by paintballs through the cracks.
We recommended a low-cost closed deck plastic pallet, but the total cost still exceeded this customer's budget. Our lightest-weight and inexpensive pallet would have fit the paintball range's budget, but the cheaper plastic pallets have a very ventilated deck.
To protect the paintball players better than wood, the plastic pallets would need to be solid. While we couldn't assist this particular customer, we still think a solid deck plastic pallet would make a great paintball bunker.
