Fiberglass Reinforced Plastic Enclosures | FRP
Fiberglass Reinforced Plastic Enclosures — Product Overview
Elevate your project with our Fiberglass Reinforced Plastic (FRP) Enclosures, engineered for unparalleled strength and durability. These enclosures feature a robust fiberglass body combined with a polymer concrete lid assembly, offering a superior solution for a range of applications. Designed to withstand the toughest conditions while remaining remarkably lightweight, they provide a cost-effective and efficient option for your enclosure needs.
Key Features
- Enhanced Strength and Durability: Our FRP enclosures are crafted with a fully fiberglass body and a polymer concrete lid, making them up to three times stronger than traditional concrete. This exceptional strength ensures superior protection and longevity, even in harsh environments.
- Lightweight and Easy to Handle: Despite their impressive strength, these enclosures are significantly lighter than traditional concrete options. This reduced weight simplifies transportation and handling, making installation faster and more efficient.
- Cost-Effective Shipping: The innovative design of our FRP enclosures allows for nesting, optimizing shipping space and reducing costs. This feature not only saves money but also minimizes the environmental impact of transportation.
- Versatile Applications: Ideal for a wide range of uses, our enclosures are perfect for applications requiring robust protection and resistance to environmental stressors. Whether for industrial, commercial, or utility settings, these enclosures deliver reliable performance and long-term value.
- Low Maintenance: The fiberglass composition provides excellent resistance to corrosion, chemicals, and UV radiation, ensuring that your enclosure remains in excellent condition with minimal upkeep.
Load Ratings (ANSI/SCTE 77)
These FRP enclosures are offered in Tier 8 and Tier 15 load classes. The full ANSI/SCTE 77 range is shown below so you can match the enclosure to your application; the classes this product is available in are highlighted.
