The strength and corrosion resistance of FRP grating are related to the glass content, resin content, resin type and method of construction. Fibergrate molded products provide an outstanding balance of corrosion resistance, slip resistance and strength.
There are three frequently used methods of support for molded fiberglass grating:
1) two continuous edge supports with bearing bars perpendicular to the supports;
2) continuous support around all sides;
3) four-corner support, or point support. (For example, pedestals are provided to support the grating a few inches above the existing floor when large volumes of liquids are flowing onto the floor and where a slip-resistant drainable floor surface is required because of operating requirements.)
Panels are normally supported around the perimeter to assure panel-to-panel alignment. In using Fibergrate’s grating, the principles are similar to metal grating usage, but you must keep in mind that the flexural modulus of elasticity of reinforced fiberglass bars is lower than that of steel. As a result, the allowable deflection is often the limiting consideration.
