With more alternative fuels being introduced to the marketplace and steel tank providers decreasing warranties due to corrosion issues, petroleum storage decisions can get complicated. Fiber Glass Systems is here to simplify the problem. FGS manufactures CSI tanks, the finest quality petroleum storage tanks for underground systems. Unlike underground steel tanks, CSI petroleum storage tanks are backed by an industry best 30-year corrosion limited warranty. Our double-wall fiberglass tanks are inherently non-corrosive, safely storing standard petroleum fluids, biofuels and biodiesels, ethanol and ethanol blends, ultra-low sulfur diesel (ULSD), even Diesel Exhaust Fluid (DEF).
