Custom Plastic Tanks

Plastic Tanks in Various Material Options: Kynar (PVDF), Lexan, PP, PVC, CPVC, & More!

Miller Plastics’ custom plastic tanks range in size from less than 1 cubic foot to more than 50 feet long.

Corrosive or harsh chemical environments require tanks with unique features.

We design and construct plastic tanks to meet the most demanding specifications.

Many of our custom-fabricated plastic tanks are annealed for maximum strength.

At Miller Plastics, we have 40+ years of experience creating single tanks, as well as integrated systems that include process piping or ancillary features for a specific manufacturing process.

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.

We manufacture plastic tanks in a wide range of shapes, sizes and dimensions in corrosion-resistant materials for a variety of uses in harsh environments.

All of our plastic tanks are fabricated with 100% virgin American-made materials.
