    What happens when an FRP product is exposed to a petroleum product?

    Petroleum-based chemicals do not degrade or corrode the FRP deck. It will not degrade the non-slip surface, but it may leave a stain. 

    De-icing chemicals do not affect FRP.  

    There are different grades of polymers used depending on the operation environment.

    What does the FRP deck coating consist of?

    A two-part polyurethane coating is applied to the visible edges and curbs for extra protection to sun and saltwater, to minimize color fading and to match client customer requirements (such as matching the steel color.)   The polymer resin has pigments and UV inhibitors as a baseline protection in the deck. 

    What fire resistance standards do FRP panels meet?

    Most of the FRP products are manufactured with a fire-resistant polyester or vinyl ester. They have a Class 1 or Class 2 rating per ASTM E84 and a Type 3 rating per NFPA 220, depending on the requirements.  The FRP is self-extinguishing and will stop burning once the active flame is removed.  

    For bridge decking, If there is a large fire on or under the bridge, then steel superstructure deformation becomes a critical issue.  Fire resistance has not been an issue for exterior FRP bridge decks and platforms in the past.

    If there are additional fire resistance requirements, there are fire proof coating that can be added at an additional cost.  

    For applications requiring non-combustible materials, a phenolic resin must be used.

    Can an FRP bridge, deck or platform be power-washed?

    Yes, FRP deck wear surfaces can be power washed.

    Do FRP products have UV protection?

    The resins, coatings, and wear surfaces that we utilize are extremely resistant to UV rays.  Direct sunlight exposure does not degrade structural performance.  There can be color fading.  Polyurethane coatings are often used to eliminate color fading.
