ProStack Product Series

The Cost Saving Solution For Bottled Water Storage & Distribution

ProStack® Product Series

The ProStack® Product Series is our premier line of storage solutions for bottled water. Plastic water storage racks are proven to be superior to metal racks for a number of reasons. Metal racks are bulky and heavy, meaning more stress on your workers who are trying to deliver them and more fuel expended by your delivery vehicles. Metal racks are also more easily damaged, so you have to replace them more often.

Polymer Solutions International, Inc. has the perfect replacement for your metal racks with our ProStack® Modular Rack Systems. In addition to being extremely durable and more efficient than metal racks, our ProStack® plastic water storage racks are fully sustainable. You can use them over and over again for years and then recycle them when they’ve reached the end of their usable life. In fact, we will buy them back from you when you are ready for new racks.


About Our ProStack® Modular Racks

These racks are made of injection-molded high-density polyethylene for durability and to better protect the water bottles they transport under sometimes-challenging industrial conditions. They offer 360 degrees of bottle enclosure, so you do not have to worry about excessive leaking issues or bottle scuffing. We have built these racks to work seamlessly with our Double Leg Ratchet Pallet, which offers double the protection from forklift damage of single leg pallets.
