ACT-100® Composite Underground Tanks
Manufactured at our Suwanee, GA fabrication plant. ACT-100® permanently bonds a heavy structural steel tank with an impermeable 100-mil fiberglass-reinforced plastic (FRP) outer shell. Provides structural steel integrity and complete fuel compatibility inside, with total electrochemical immunity outside—requiring no sacrificial anodes or cathodic monitoring.
Why Choose ACT-100® Composite
Steel + FRP Fusion
Combines structural steel load-bearing capacity with seamless 100-mil fiberglass laminate that never rusts or corrodes.
Zero Anodes Needed
Because the non-metallic FRP cladding completely isolates the steel from earth, no cathodic anode testing or monitoring is required.
10,000V Holiday Tested
100% of the exterior surface undergoes high-voltage spark testing before leaving our Suwanee plant, ensuring pinhole-free defense.
30-Year Warranty
Protected by the Steel Tank Institute 30-year limited warranty against external corrosion and internal structural failure.
