Superior Tank Co., Inc. was founded by Jess E. Marquez with the goal of building a better tank. Jess pioneered the use of powder coating with steel storage tanks which has proven to be extremely durable. Our investment in new technology, processes and equipment has further improved the quality and performance of our tanks and has earned our manufacturing facility an ISO 9001:2015 / API SPEC Q1 Certification for quality assurance.

To serve a greater number of customers and install our bolted tanks throughout the USA, we have expanded our manufacturing and operations capacities in Texas and California. Even though the company has grown, Superior Tank remains family owned and operated and we truly value the relationships we have established with our customers over the last three decades.
