Who We Are
Houston PolyTank is the U.S. engineering authority behind high-performance HDPE and PP structures for industrial and municipal systems. Every structure we produce is custom-engineered and built to order — designed around your application, your chemistry, your environment, and your operational requirements.
We do not manufacture off-the-shelf tanks. We build extrusion-wound, monolithic structures engineered to outperform steel, fiberglass, and concrete in the harshest industrial environments, including the only patented extrusion-wound rectangular HDPE tank design manufactured in the U.S. (U.S. Patent No. 10,150,264B2).
What We Do
Many of our clients report tank failure due to bulging in thin-walled, roto-molded tanks. When these competitor tanks fail to meet their needs, our customers turn to us to help.
We solve problems like these with our industry-leading tanks, which are:
- Structurally Sound: Our tanks are the high-performance alternative to traditional carbon and stainless steel, fiberglass, and roto-molded plastic tanks.
- Low Maintenance: Our tanks are essentially maintenance-free; no need to sandblast or repaint because tanks are colored by an additive to the plastic.
- Long Lasting: Our tanks have walls up to three inches thick; they don’t buckle, bulge, oxidize, or corrode like other tanks.
- The Ideal Solution for Challenging Applications: Our tanks are the perfect solution for storing even the strongest and hardest-to-contain chemicals; our clients use our tanks to store sulfuric acid, sodium hypochlorite, nitric acid, and hydrochloric acid.
- Tanks Are Perfect As Reactor & Process Applications
Our team manufactures to the highest of standards. Our tanks are available in high-density linear polyethylene and polypropylene models.
We always work with:
- FDA approved materials
- Certified Welders of Thermoplastic Welding
- A rigorous quality control process (we monitor and document QC requirements throughout the manufacturing process)
- A mandatory 24-hour hydro test to ensure integrity
- Further air tests upon client request
Versatile, High-Quality Products
At Houston PolyTank, we manufacture large-volume polyethylene and polypropylene tanks, silos, pipe, and ductwork.
Tanks
Our tanks are made by extruding polyethylene or polypropylene around a drum mold. Tanks range from 50 gallons to 50,000 gallons in capacity and are ready for installation immediately.
Pipes and Ductwork
Our manufacturing capabilities don’t just allow us to create large-volume tanks. We’re also a proud supplier of high quality, thick-walled pipes. You can ask a customer service representative for more information about our pipe and ductwork offerings.
Accessories
We use unique manufacturing methodologies. These practices allow us to offer our customers a broad range of accessories. We stock a wider range of options than most other plastic tank manufacturers.
How We Do It

Our engineering and manufacturing approach is built on proven, industrial‑grade methods.
Extrusion‑Wound Monolithic Construction
Creates a seamless, continuous structure with no weak points — engineered for long‑term structural integrity.
DVS 2205 Compliance
We follow the industry’s most rigorous design and fabrication standards for thermoplastic structures.
Certified Thermoplastic Welding
All fabrication is performed by certified thermoplastic welders trained to the highest standards of polymer joining.
Factory QA + Hydro‑Testing
Every tank undergoes a mandatory 24‑hour hydro test, with optional air testing available upon request. We document and verify QC requirements throughout the manufacturing process.
Material Science Expertise
We engineer HDPE and PP structures based on chemical compatibility, load requirements, and environmental conditions; including applications involving sulfuric acid, sodium hypochlorite, nitric acid, and hydrochloric acid.
Built-to-Order Manufacturing
Every tank, pipe, and structure is fabricated to your exact specifications. No standard catalog sizes. No compromises.
This is engineering‑first manufacturing – precise, repeatable, and evidence‑driven.
Your Source for Large-Volume Tanks
Houston PolyTank, LLC formed in 2010 to introduce the extrusion wound plastic tanks to the United States market. The company formed a partnership between a steel manufacturing company, J.L. Houston. The manufacturing plant was built from the bottom up in Hopkins, Missouri. Six months later, we started production of the extrusion wound plastic tanks.
Today, the company doubled the number of original molds and has the capability of manufacturing 50 to 50,000 gallon plastic tanks. Houston PolyTank has customers all around the U.S. and Canada, and our tanks are installed and operating from Long Island in the East Coast to Southern California in the West and Alaska.

Our Story
Houston PolyTank was founded to solve a critical gap in the U.S. market: the need for engineered, corrosion‑proof alternatives to concrete, steel, and fiberglass. Traditional materials were failing in harsh industrial and municipal environments, and no domestic manufacturer was delivering extrusion‑wound, monolithic HDPE at scale.
We built that capability from the ground up.
Formed in 2010, we constructed our Hopkins, Missouri facility specifically for extrusion‑wound thermoplastic manufacturing – built exclusively for custom, made-to-order fabrication at industrial scale. Since then, we’ve expanded our capabilities, doubled our mold inventory, and grown into a trusted engineering partner for industrial processors, water and wastewater systems, chemical facilities, and municipal infrastructure teams across North America.
Our engineering expertise also powers MagnaPlast™, the 100‑year, patent‑pending HDPE sewer manhole redefining underground infrastructure.
Why Choose Houston PolyTank
Customers choose us because our structures are engineered to deliver:
Corrosion‑proof performance
Longer service life
Lower lifecycle cost
Easier installation
Industrial‑grade reliability
Built‑to‑your-exact-specification flexibility
Many customers come to us after experiencing failures in thin‑walled, rotomolded tanks — bulging, cracking, and chemical attack that compromise safety and operations. The difference with Houston PolyTank is fundamental: every structure is built to your exact specification, engineered to your application requirements, chemistry, temperature range, and structural loading – not adapted from a standard mold or catalog. Custom-engineered, monolithic, extrusion-wound construction built specifically for your environment. No compromises.
When reliability matters, engineering matters— that’s where Houston Polytank leads.
Our Commitment
We stand behind every structure we build.
Our commitment is simple: to engineer custom HDPE and PP solutions that outlast traditional materials, perform in environments where failure is not an option, and deliver long-term value to every customer and every application we serve.
That commitment is built into every tank, every pipe, and every structure that leaves our Hopkins, Missouri facility.
