Leading the industry

Paso Robles Tank is a trusted field-erected tank contractor delivering aboveground welded steel storage tanks that serve as the backbone of industries worldwide—providing the reliability and performance operations depend on every day. For over 30 years, we have built a reputation for excellence by helping customers successfully complete complex tank projects with confidence.

We specialize in the design, engineering, fabrication, erection, and repair of tanks, with a core focus on API 650 and 620 construction, API 653 repairs, API 12D tanks for industrial applications, and AWWA D-100 tanks for municipal and water systems.

We understand the constant pressure of managing deadlines, budgets, and complex workloads. Choosing the right partner for your storage tank project shouldn’t add to that burden. That’s why we provide a streamlined, worry-free experience from start to finish—built on clear communication, dependable execution, and a commitment to getting the job done right.

Serving a diverse range of clients—from large corporations to independent owners and operators—we offer fully integrated in-house engineering and fabrication capabilities. This allows us to design and build custom storage tanks while delivering tailored repair solutions that meet your exact specifications. Our focus on quality, safety, and precision ensures every project meets the highest standards. Our company motto, “Safety + Quality = Production,” embodies this commitment and drives everything we do in the field and in the shop.

Our experience spans a wide range of markets, including water and wastewater infrastructure, data centers requiring reliable backup and cooling solutions, thermal energy storage systems, molten salt storage for renewable energy applications, and the demanding oil and gas industry—along with many other specialized industrial sectors. This breadth of expertise allows us to adapt to unique project requirements and deliver solutions that perform in even the most challenging environments.

From concept through completion, our experienced team has the expertise to execute all types of tank construction and repair projects, so you can stay focused on running your business with confidence.
