Aboveground FRP Tank
Aboveground FRP tanks (fiberglass-reinforced plastic) are a shop-fabricated, atmospheric-pressure storage solution used where carbon steel is unsuitable due to corrosion and where polyethylene lacks the structural rigidity or temperature tolerance the application demands.
The material is a thermoset resin and glass fiber composite; resin selection — orthophthalic, isophthalic, or vinylester — is matched to the stored liquid, concentration, and operating conditions and is the primary compatibility driver. Tanks are available in vertical and horizontal orientations and are built to order with connections, fittings, and access points specified to your project. Submittal documentation is typically available from the manufacturer.

Aboveground FRP Details
Aboveground FRP storage tanks are specified across industrial, municipal, and facility applications where corrosion resistance, chemical compatibility, and long service life are the primary drivers. The material is well-suited for situations where carbon steel would corrode and where polyethylene lacks the structural rigidity or temperature tolerance required for the application.
FRP is substantially lighter than steel, which reduces transport, handling, and foundation load requirements without sacrificing structural performance. Tanks are available in vertical and horizontal orientations — as well as cone bottom, open top, and mix tank configurations — to fit site layout and process needs. Connections and access points are project-specific; inlet, outlet, vent, overflow, drain, and manway options are configured at time of order.
Resin selection — isophthalic polyester, vinylester, or a special-order system — is matched to the stored liquid, concentration, and operating temperature and is the primary compatibility driver. Confirm compatibility during quoting. Submittal documentation, including cut sheets and drawings, is typically available from the manufacturer.

Frequently Asked Questions
Common questions about aboveground FRP tank specifications, compatibility, and ordering.
What is an FRP Tank?
Fiberglass-reinforced plastic -- a glass fiber and thermoset resin composite that provides structural strength with corrosion resistance where steel would corrode or polyethylene lacks the required rigidity or temperature tolerance.
What Aboveground FRP Tank do you provide?
Vertical (50 to 50,000 gal, 2'--14' dia.) and horizontal (25 to 6,000 gal, 23"--90" dia.).
How do I know what chemicals are compatible with my FRP Tank?
Compatibility depends on the stored liquid, concentration, and operating temperature. See our Chemical Compatibility Chart to check your tanks chemical compatibility or uou can provide these when requesting a quote and the appropriate resin system will be confirmed. Never assume compatibility based on tank material alone.
Can fitting and connection be configured to my specs?
Yes, tanks are built to order with connection locations, sizes, and types specified at time of order. Provide your requirements when requesting a quote.
