1984: Superior Tank is Founded

Based on decades of steel tank expertise and confident he could build a better tank, Jess Marquez embarked on a decades long adventure. With his family at his side, Jess founded Superior Tank Co., Inc. and purchased a small manufacturing facility in Santa Fe Springs. Hard work was part of Jess’ nature and he began a legacy lasting decades which changed the steel tank industry.

2017: Another Distinguishing Certification

The latest addition to our collection of certifications is the NSF 61/372 Certification of our bolted steel tanks. This special certification signifies our bolted tanks can be approved for storage of drinking water and meet specific material and design criteria.

2017: One step closer to the East

The latest part of our story continues as the powder coating line in our Texas Manufacturing Facility is installed and becomes fully operational. Equipped with some of the most advanced coating equipment, our Texas facility is able to produce powder coated tanks at the same level of quality as our California bolted tank manufacturing plant.

2016: The Legacy Continues

Upon the retirement of Jess Marquez, his son, James Marquez proudly assumes the role of President / CEO.  With decades of experience in the bolted and welded storage tank industry and skilled in leadership, James continues the family legacy of integrity and customer service.

2015: The Innovation Continues

With decades of experience and history manufacturing powder coating bolted steel tanks, we introduced our exclusive Silica Zirconium (SiZr) undercoating. This seal is designed to reduce the spread of corrosion and lengthen the lifespan of our powder coating. Laboratory testing has proven the SiZr seal significantly reduces corrosion damage if the powder coating is damaged by significant impact and can make the difference between a small coating patch and a major coating repair.

2014: Testament to Our Quality

Thanks to a proven record of quality and implementation of stringent quality processes, Superior Tank earned the prestigious API Spec Q1 ISO 9001 certification for quality assurance. We are very proud of this certification as it is the culmination of considerable effort to implement a comprehensive Quality Management System (QMS). Our QMS ensures our tanks meet or exceed our customers’ expectations and are delivered on time. We always knew our tanks were outstanding quality and now we have the proof!

2014: The Choice is Yours

Progress is a way of life for us and support this philosophy, we introduced a line of flat panel bolted steel tanks to expand our product offering. Our flat panel tanks provide all the benefits of our chimed bolted steel tank and are available in sizes up to 2,500,000 gallons.

2013: The Standard for Fire Protection

To meet the needs of our international customers, Superior Tank achieved FM Certification for our bolted steel tanks designated for fire protection. This internationally recognized standard provides our customers confidence in the level of quality of our bolted tanks for water storage.

2013: The Growth Continues

To fulfill increasing demand for our bolted tanks in the Midwest, we moved our Texas location to a larger facility in Rosenberg, TX. The relocation supports our long-term expansion plan includes a warehouse for faster delivery of parts throughout the Midwest and the Atlantic Coast. Furthermore, the facility is large enough to accommodate all the equipment for bolted steel tank manufacturing and powder coating.

2007 : Tanks Built by Bots

Always looking to advance the precision of our tanks, Superior Tank began a significant investment in the latest manufacturing technology. New machinery included a computer guided turret computer guided turret punching press which perfectly creates bolt holes in tank staves without deforming the steel and any rough edges. Shortly thereafter, a robotic welding arm was installed providing accurate and precise welds on tank nozzles, ladder and other accessories. The new equipment ensures our bolted tanks and components for our welded tanks are precision crafted.
