Wide Selection of Fiberglass Tanks for Sale

Fiberglass storage tanks offer a durable and reliable solution for liquid storage in agricultural facilities, commercial properties, and areas with limited water access. They can store water for fire sprinkler systems or serve as a supplemental water source for firefighting operations. These tanks meet AWWA and NFPA 22 standards for private fire protection, making them an excellent choice for fire suppression. Each fiberglass tank is also built to meet or exceed ASTM specifications.

Also known as fiberglass-reinforced plastic (FRP) tanks, these bulk storage units are among the strongest liquid storage options available. They are highly valued for their corrosion resistance and ability to withstand extreme weather conditions. All of our fiberglass tanks are proudly made in the USA.

Who Uses Fiberglass Water Tanks?

Fire Protection Engineers & Designers

Specify fiberglass fire protection tanks and dedicated fiberglass water tanks as fire water reservoirs for commercial, industrial, and institutional buildings. They rely on AWWA- and NFPA 22-compliant fiberglass-reinforced plastic (FRP) tanks to provide reliable storage for sprinklers, standpipes, and private fire mains in locations where municipal supply is limited or interruptible.

Facility & Property Managers

Manage water storage for campuses, warehouses, remote operations, and mixed-use properties. Fiberglass storage tanks give them a corrosion-resistant, low-maintenance way to maintain fire water reserves, emergency backup supply, and process water without constant repairs or repainting.

Contractors & Design-Build Teams

Integrate fiberglass tanks and FRP tanks into new construction and retrofit projects when they need fast installation, predictable freight, and flexible sizing. Sectionalized designs and custom fittings help them meet site constraints, local codes, and project timelines.

Fiberglass Fire Protection Tanks

Standard fiberglass water tanks are highly durable and built for safe, long-term liquid storage in residential, commercial, and industrial settings. These tanks can be engineered to store a wide variety of liquids and are available in multiple configurations. Options include vertical and horizontal tanks, chop-hoop filament-wound fiberglass tanks, and centrifugally cast fiberglass tanks, all offered in a range of sizes and designs.


Sectionalized fiberglass tanks are ideal for retrofit fire protection systems in residential and commercial properties. Each tank includes assembly instructions and adhesives for straightforward on-site installation. While not recommended for aggressive chemicals or food-grade storage, sectional tanks are widely used in fire suppression systems. We also offer poly tanks and corrugated steel tanks as alternative water storage options.
