Warminster’s one-piece molded FRP shelters are built as a single, fully reinforced structure for maximum strength and long-term performance.
With no panel joints and no field assembly required, these shelters offer exceptional protection against moisture, chemicals, and extreme weather.
Our molded shelters are commonly used for:
Because FRP does not rust, rot, or corrode, these shelters outperform metal, concrete, and wood alternatives in demanding conditions.
Building the entire enclosure as a single molded unit provides several engineering advantages:
Each shelter is built using hand-layup fiberglass laminates for maximum durability and long service life.
Although molded as a single unit, every shelter can be tailored to meet project requirements. Available options include:
If you can provide drawings or basic requirements, we can build to your dimensions and configuration.

Our one-piece molded FRP shelters are manufactured using materials that meet ANSI/AWWA F101 standards for fiberglass construction. Depending on the project, we can also produce shelters in compliance with:
Buy America / Build America (BABA)
American Iron & Steel (AIS)
Project-specific engineering requirements
Built for decades of service, these shelters require virtually no maintenance and hold their structural integrity even in harsh chemical environments.
