reliable and safe storage of fuel products

Plasteel® Elutron®

Double Walled Steel / Fiberglass Jacketed Fuel Storage System

Steel tank fuel containment systems have a well-established history of providing reliable and safe storage of fuel products including gasoline, diesel, ethanol, JET A, AVGAS, and Diesel Exhaust Fluids (DEF). Plasteel® Elutron® underground fuel storage tanks incorporate the time-proven strength and reliability of steel tanks with a unique impervious fiberglass reinforced (FRP) outer secondary containment layer. This seamless outer FRP layer creates a barrier that protects the steel tank from the potentially corrosive effect of underground environments.

The 360º interstice between the steel and FRP secondary containment is created by incorporating an aluminum foil layer that provides a system for monitoring inner tank integrity. The UL Listed Elutron® Double-Walled Fiberglass Jacketed tank system meets the EPA 40 CFR subpart B, 280.20 standards for new underground gasoline storage tanks.


  • Reliability: No documented external corrosion failure of any Plasteel® tank.
  • Satisfaction: 30-year Limited Warranty
  • Sizes and Capacities: 560 to 40,000-gallon capacity, 4 to 12 feet in diameter
  • Versatility: Compatible with gasoline, ethanol blends from E10 to E100, diesel, bio-diesel blends from B2 to B100, fuel oil, methanol, and isobutanol and additives (Can be lined internally for special applications e.g., DEF, jet fuel, non-potable water storage)
  • Customization: Available with multiple compartments for multiple fuel storage 
  • Cost-effectiveness: Lower installed cost than fiberglass underground fuel storage tanks due to less excavation and backfill material. Learn more about Excavation/Backfill Comparison here.
  • Sustainability: Steel is 100% recyclable


Quality is built into every tank system TrueNorth Steel fabricates. Our production facilities are certified and regularly audited by the American Petroleum Institute, Steel Tank Institute, and Underwriters Laboratories.

TrueNorth Steel is a reliable partner with over 75 years of experience fabricating a wide array of superior steel tank products, including horizontal and vertical tanks, single-wall and double-wall above-ground fuel storage tanks, Fireguard® protected fuel storage systems, Flameshield® fire-tested tanks, and petroleum storage tanks for oilfield applications.

All of our welders are American Welding Society certified and TrueNorth Steel maintains a comprehensive Quality Management System that guides each aspect of our steel fabrication, including sourcing, planning, and manufacturing processes.


Installation of Elutron® underground storage tanks is simple and easy due to their inherent stiffness when compared to fiberglass tanks which require deflection monitoring during backfilling. Elutron® underground fuel tanks usually require a smaller excavation footprint and less backfill while fiberglass tanks require higher-quality gravel backfill and a greater distance between adjacent tanks.

TrueNorth Steel tanks are easy to install and arrive with precast concrete deadman anchors and either steel or polyester tie-down straps.

Elutron® underground gasoline storage tanks can be supplied with a factory-established interstitial vacuum. Prior to delivery, our team cleans and levels all the fittings and marks the center lines on each tank. These details save installers several hours of work normally spent on the pre-installation testing and cleaning of non-metallic tanks.

TrueNorth Steel delivers Elutron® underground fuel tanks with vacuums applied and center lines marked to simplify and expedite installation.


Elutron’s unique and time-proven double-walled, fiberglass jacketed tank technology provides reliable performance, safety, and ease of installation.

  • The inner steel tank is designed to contain gasoline, JET A, AVGAS, Diesel, DEF, and methanol/ethanol in varying concentrations.
  • The outer fiberglass “FRP” jacket and inner steel tank are separated by an interstitial space allowing monitoring of tank integrity.
  • The outer FRP jacket acts as a corrosion barrier against aggressive and corrosion underground conditions ensuring outstanding long-term tank performance
  • The UL Listed Elutron® Double Walled Fiberglass Jacketed tank system meets the EPA 40 CFR subpart B, 280.20 standards for new underground storage tanks.
  • Tank built and tested in accordance with UL58 Steel Underground Tanks for Flammable and Combustible Liquids, and UL1746 External Corrosion Protection Systems for Steel Underground Storage Tanks.
