Engineered HDPE Tanks Built to Outlast

Houston PolyTank designs and manufactures high-performance HDPE and PP storage tanks engineered for demanding industrial and municipal applications. Our tanks are built to replace steel, stainless steel, fiberglass, and rotomolded plastic in environments where corrosion resistance and long-term reliability matter most.

At Houston PolyTank, we don’t just build storage and containment systems—we engineer the technologies that advance the industry.Driven by a commitment to innovation, our patented processes and systems, including our patented rectangular tanks, hybrid pipe-forming processes, and patent-pending MagnaPlast™ HDPE manholes, deliver unmatched performance. These exclusive technologies allow us to set the industry standard for durability, chemical resistance, and long-term reliability.

Our extrusion-wound construction eliminates weak points, will not bulge, resists corrosion, and delivers superior long-term performance across a wide range of applications. With wall thicknesses ranging from 1/2 inch to 2.5 inches, these tanks are engineered for aggressive chemicals, high-stress processes, and mission-critical storage.

We select the right material for the operating conditions:

• High-density linear polyethylene (HDPE) for applications up to 120°F.

• Polypropylene (PP) for high-temperature applications up to 180°F for chemical applications and 200°F.

Every tank is custom-engineered around chemical compatibility, operating temperature, specific gravity, dimensions, structural loading, and the application environment. Every tank, pipe, and manhole we manufacture starts with your application and ends with a system engineered to outlast it.
