Superior Tank offers both bolted and welded steel storage tanks for oil storage. Our bolted steel tanks install in 1/3 of the time compared to other tank designs and incorporate extremely durable Buna N gaskets to eliminate leaks. We offer Scotchkote powder coating on our bolted tanks to withstand oil and other corrosive liquids. We are one of the few tank manufacturers certified to provide tanks featuring the prestigious API 12B Monogram. In addition to bolted tanks for oil storage, Superior Tank Co., Inc. fabricates and erects welded steel tanks. All of our oil storage tanks can equipped with appurtenances specific to oil storage such as thief hatches, spiral staircases and exterior roof rafters.
