Harrington Offers a Wide Variety of FRP Structural Shapes

Fiberglass-Reinforced Polymer (FRP) Tanks

Fiberglass-reinforced polymer (FRP) tanks are plastic tanks that have been structurally reinforced with fiberglass, similar to the way that rebar strengthens concrete. Fiberglass tanks are ideal storage solutions for outdoor rainwater harvesting, water storage, fire protection, oil field storage, liquid fertilizer, water treatment, irrigation water storage, and much more.
