| FRP pultruded grating is specially fabricated for applications that call for high strength and large span. Since fiberglass is the key contributor to grating's strength the content of fiberglass in gratings turns out to be a major factor. iGRID pultruded gratings can contain around 55% fiberglass, which can guarantee the high strength of gratings. |

 |
|
| The grating is made by pulling thermoset resin together with fiberglass through a heated mold with temperature control at different sections of the die to facilitate resin to cure. |

Under normal conditions, these bearing bars, after drilling holes in them, are assembled with cross bars at a spacing of 6". ( Of course, the spacing can be adjusted as per customer's requirement. )
