Various companies sell bolted steel tanks, but there is only one “Superior Tank”. Is there really a difference between bolted tanks manufactured by Superior Tank Co., Inc. (STCI) and bolted steel tanks and glass-lined bolted steel tanks made by other companies? The answer is in short “yes” for various reasons including STCI’s precise manufacturing processes, premium raw materials, extensive company history, API SPEC Q1 / ISO 9001:2008 certification and outstanding customer service. Superior Tank Co., Inc. is one of the few bolted tank manufacturers in the United States and the only bolted tank company with manufacturing facilities in both California and Texas. Owning and operating State-of-the-Art manufacturing facilities gives STCI complete control of the quality of our bolted tanks and we are not reliant on outside companies for the quality of our bolted steel storage tanks. All of our bolted tanks use quality materials such as heavy duty Grade 5 or Grade 8 high tensile strength bolts and the steel used for our bolted tanks is verified to meet specific quality standards such as surface quality, edge quality, silicone content, squaredness and flatness. In addition, our specially formulated powder coating and corrosion preventing SiZr seal maximize the lifespan of the epoxy coating of the bolted tank. Our heavy duty gaskets ensure our bolted tanks remain in service and do not require storage tanks to be taken offline to replace the mastic which is used with glass-fused-to-steel bolted tanks. We have invested heavily in precision equipment such as CNC machinery, Automated Robotic Technology (ART), and advanced turret punches to ensure our bolted steel tanks are manufactured with exacting precision. As our bolted steel tanks are crafted with such accuracy, components fit together perfectly, eliminating tank leaks and field rework. To confirm our bolted tanks meet or exceed quality standards, STCI has implemented various Quality Management Systems and is API SPEC Q1 / ISO 9001:2008 certified. Various processes and procedures have been put into place to ensure our bolted steel tanks meet customer expectations and delivery schedule. In addition, STCI has earned the reputation of providing exceptional customer service and ensuring our customers are happy with their new epoxy coated bolted tank. The results of these extra efforts are illustrated in our excellent Customer Satisfaction rating and customer testimonials. When all of these factors are considered, it is evident what makes our tanks, “Superior”.
