Corrosion Resistant

FRP is corrosion resistant making it ideal for chemicals, water, wastewater, fertilizer, oil and gas, and more. Paired with the right liner, FRP is safe for even the most corrosive of substances.

Light Weight

Generally speaking, FRP weighs about 75% less than steel. Installation costs are reduced since heavy-lifting equipment is not needed. We can also provide the delivery and installation.


Because FRP tanks are strong as steel, have less maintenance costs, and last 20-30 years, the result for you is they are an economical investment over the lifespan of the product.


Fiberglass can be molded into any design and are easily customizable. With up to 60k gallons, large capacity tanks can be factory-built which has many advantages over field-erected tanks.
