Underground Fuel Tanks

Nationwide’s fiberglass fuel tanks are the most corrosion-resistant tanks in the market today, meeting the most stringent requirements of the UL 1316 Third Edition. This provides our customers confidence for longstanding hassle-free service. Our corrosion-resistant fiberglass tanks are compatible with all ethanol-blended fuels, biodiesel, and ultra-low sulfur diesel fuels. Fiberglass inherently provides corrosion resistance from external forces as well, as they are not vulnerable to corrosion. While cathodic protection and coatings are used to stem the corrosion issues of steel tanks, these add cost and are not a complete solution, still leaving steel tanks susceptible to corrosion. Our superior structural design and innovative resin technology give our customers confidence that they are choosing the best petroleum tank available on the market today. 

Fuel Tank Installation

Compartment tanks offer multiple benefits to the retailer. The double-walled tank is divided by a double-walled bulkhead to create multiple compartments. The ability to store multiple fuel blends in one tank lowers the excavation, permitting, inspection, and shipping costs. This enables the retailer to offer multiple fuel selections where site restrictions may have prevented doing multiple single compartment tanks in the past and adds flexibility to meet customers’ changing demands. As multiple compartment petroleum tanks grow in popularity, the environmental and cost-saving advantages of Nationwide Tanks’ independently monitored compartments offer the versatility to only have one compartment down if any issues arise while the tank is in service. This also ensures the ability to pinpoint issues quickly while limiting downtime and lost revenue.
