- FRP, a composite material, is composed of a polymer matrix reinforced with fibers, typically glass or carbon. The combination of these elements imparts FRP pipes with outstanding mechanical strength, making them ideal for high-pressure and high-temperature applications. Moreover, their lightweight nature simplifies handling, installation, and transportation, reducing overall project costs.
Meniscus Top: The concave surface, or half-moon cross-section has no grit. This molded meniscus top grating provides superior slip-resistant footing in most environments including wet or oily conditions and is the standard surface for all Specialty Steel’s molded gratings.

Our fiberglass structural shapes and pultruded fiberglass profiles are made from a combination of fiberglass and thermosetting resin systems. All shapes are lightweight, impact resistant, low maintenance, non-magnetic, low conductive, and have dimensional stability, making them easy to install and ideal for several applications. Custom shapes are available upon request. For more on fiberglass structural shapes, click here.









To help make installations safer, Openchannelflow offers Fiberglass Grating Covers for its line of flumes and Packaged Metering Manholes. Using a unique narrow opening grating, Openchannnelflow molds in a support channel at the top of the flume. The fiberglass grating is then cut to size and nestled into the flume.
