FiberSPAN™ Fiber Reinforced Polymer (FRP) composite panels are created from corrosion-resistant polymers reinforced with glass fibers for strength and stiffness. FRP panels provide a prefabricated, corrosion-resistant superstructure that can withstand harsh outdoor conditions, chemical exposure, and heavy traffic. In addition to providing exceptional structural reliability and strength, FRP double tee panels are fire-resistant, consistent with NFPA 130 and ASTM E-84 Class 1 standards.
The Double Tee panel offers a lightweight, durable solution for structural projects such as bridge decks, rail platforms, and bridge sidewalks needing to carry high loads over long spans. The fast installation of large surface area has made FRP Double Tee the preferred panel for rail platforms.
A double tee is a load-bearing structural component that looks like two T-beams next to each other. It consists of two vertical legs, also known as stems or webs, and a horizontal piece called the flange along the deck. The flange
and webs are integrally molded for an exceptionally reliable structure capable of supporting heavy loads.
Precast concrete double tees have been used in the construction industry for more than 50 years, due to the stability of the design. FRP double tees are designed using the same model, but with much lighter FRP material that’s easier to mold, transport, and install. In fact, FRP double tees are approximately 80% lighter than their precast concrete counterparts, with a weight of 15–22 pounds per square foot (psf) versus concrete's hefty 120-130 psf.
Since they were developed in 2008, Composite Advantage’s FRP double tee panels have been used in a broad range of structurally critical applications, including road bridges and pedestrian bridges. As the FRP technology advances, the prefabricated lightweight panels offer great value in rail platform rehabilitation applications and new construction since the panels can be quickly installed around train schedules.
FRP is significantly lighter than concrete and other structural materials while maintaining exceptional load-bearing capabilities and tolerance for heavy traffic.
FRP decks and stems are molded in one solid piece, which ensures their structural integrity.
The single-piece construction and lightweight characteristics make FRP tee panels easy to install, thereby reducing installation time, labor, and effect on platform usage.
FRP double tee stems can be customized to meet specific size requirements, so they can be full length or transition, similar to dapped end beams for traditional concrete double tees. In addition, designs can be modified for easy integration into existing structures, and specialized triple tees can be manufactured for applications with depth restrictions.
In addition to FRP's material advantages, Composite Advantage offers a variety of features, including crown or cross-slope surfaces, non-slip polymer overlay, warning tactiles at platform edges, curbs, embedded attachment points, drain scuppers, and notch-outs for supplemental structures. Our customizable double tee panels offer tailored design and easy installation for both existing and new structures.
FRP panels are capable of spanning support piers up to 50 feet apart while retaining structural integrity and load-bearing capabilities.
FRP material is extremely resistant to corrosion, chemicals, and harsh environmental conditions. While concrete can experience significant wear if it’s exposed to deicing chemicals, FRP material can withstand these compounds easily, making it ideal for using on platforms and walkways.
FRP is significantly less expensive to mold, transport, and install compared to concrete and other structural materials. Since it’s exceptionally durable and corrosion-resistant, it’s also significantly less expensive to maintain and requires fewer repairs than traditional concrete and steel structural
FRP materials are manufactured to meet NFPA 130 & ASTM E-84 Class 1 standards for fire-resistance.
