Pultruded Fiberglass Grating



 

BENEFITS OF PULTRUDED FIBERGLASS GRATING:

  • Corrosion Resistant
  • Non-Conductive
  • Low Maintenance
  • Fire Retardant - ASTM E84, Class 1, F.S. 25 or less
  • Extended Service Life
  • Superior Strength in load bar direction
  • In many cases, fewer supports are required, which can result in a lower cost system
  • Less wasted material

American Grating’s Pultruded FRP Gratings are assembled from pultruded shapes. These shapes (I-Bars, T-Bars, etc.) are manufactured by pulling fiberglass rovings and mats through guides, then into a resin bath, then wrapped with a surfacing veil, then finally pulled through a heated die to form the desired bar shape. Once the bars are pulled, they are drilled for crossrods, then assembled by installing the crossrods spaced on 3” or 6” centers (depending on the grating type). These crossrods, that lock the bars into place, are then bonded with epoxy to ensure the bars will not move. Pultruded gratings are typically manufactured with either an Isophthalic Polyester Resin or a Vinyl Ester Resin, but can be manufactured in any resin available.

See our Chemical Resistance Guide and Resin Selection Guide for more information and to determine which resin system is right for your application.

Since Pultruded gratings are manufactured by pulling and assembling load bars and positioning those bars as needed to create panels as required, in addition to our standard panel sizes, we are able to reduce the waste material by manufacturing custom panels to size. We pultrude load bar lengths as required and assemble panels to required widths. There is no need to manufacture a full panel and waste material. In addition, we are able to custom manufacture panels of various sizes and standard styles listed below. Contact us today with any custom requests.

Pultruded grating load bars are manufactured with 65% glass rovings, and 35% resin, which increases the strength of the grating and allows for higher loading and longer spans than molded gratings. This can translate into fewer supports. Additionally, Pultruded gratings are unidirectional and only need to be supported on the ends of the bearing bars, not on all (4) sides. 




Pultruded Gratings are commonly used in a variety of applications, including, but not limited to:

  • Sunscreens
  • Benches
  • Platforms
  • Bridges
  • Walkways
  • Trench Covers
  • Manhole Covers
