Our bolted tanks are engineered and manufactured to AWWA D103 standards as a specified, cost-effective alternative to field-welded tanks. We combine in‑house engineering, automated fabrication, and a 1,000‑foot coatings line to deliver attractive, long‑lasting bolted-panel tanks for water, wastewater, dry storage, and fire‑protection applications.
The Industry Leader in Steel Bolted Tanks
Since our inception in 2000, our goal has been to set the standards in the carbon welded steel tank industry. In 2016, we entered the bolted tank market with the launch of our Bolted Tank Division. The state-of-the-art Bolted Tank production line is located in our 65,000 square foot facility in Hemet, California. We created a process that guarantees the highest quality bolted tanks, and we are known for the most consistent coatings on all tanks we manufacture.
We take great pride in leading the industry in engineering, fabrication, civil construction, painting, and coatings. We also offer modifications, tank repairs, and maintenance of above-ground storage tanks. Our bolted tanks are designed to the rigorous AWWA D103 standards as a specified alternative to field-welded and coated tanks. With our streamlined and fully automated 1,000-foot coatings line and the support of our in-house engineering staff, we excel at quickly and cost-effectively meeting our customers’ needs for water/wastewater, dry storage, and fire protection water applications.

Our Experience With Bolted Tanks
Our bolted tanks are factory-made in modular panels and assembled on-site. That approach shortens installation time, lowers transportation cost, and gets a reliable tank into service faster than field-welded construction. Every panel arrives finished and ready to bolt together, so a new tank goes up quickly with dependable, long-term results.
If you are weighing a bolted tank for a new project or an expansion, our team can walk you through the sizing and site options that fit your application.
