Custom Plastic Tanks

Custom plastic tanks from Unit Liner Company range in size from less than 1 cubic foot to more than 50 feet long. Rectangle, square, round, or custom shape. Tanks can be constructed with inlets or outlets as needed. Corrosive or harsh chemical environments require holding tanks with robust features. Many of our custom-fabricated plastic tanks are annealed for maximum strength. Self-supporting tanks can be reinforced with plastic-encapsulated steel bands or internal baffles to minimize sidewall bowing. Welds are smooth and burr-free to minimize sediment buildup and allow for easy cleaning. All edges and components are CNC cut, nothing ships with saw cut edges, Burrs, or sharp edges. We provide custom plastic tanks in a wide range of shapes, sizes, and dimensions in corrosion-resistant materials for a variety of uses in harsh environments. Various material options are available: Kynar (PVDF), Lexan, PP, PVC, CPVC, and More!

All tanks are inspected and water tested before shipping to ensure no leaking!
