The industry leader in bolted tanks
Paso Robles Tank has set standards in the carbon welded steel tank industry since our inception in 2000. In 2016 we expanded into the bolted tank market with the launch of our Bolted Tank Division, operating a state-of-the-art production line in our 65,000 square foot facility in Hemet, California. By partnering with the best names in the business, we built a process that guarantees the highest quality and most consistent coatings for every tank we manufacture.

Our bolted tanks are designed to the rigorous AWWA D103 standard and are a specified alternative to field-welded and coated tanks. With a streamlined, fully automated 1,000-foot coatings line and the support of our in-house engineering staff, we deliver bolted tanks for water and wastewater, dry storage, and fire-protection water applications — quickly and cost-effectively.
