Characteristics of Different Types of FRP

feng1Molded Grating typically has a square mesh pattern similar to a checker board whereas PULTRUDED grating is made from a series of Parallel Bars. Pultruded Grating consists of a series of parallel bearing bars. The bearing bars typically have a ‘T’ or ‘I’ shaped profile. The closer the bearing bars are together, the stronger the grating. Cross-rods are not intended to be applied in the span direction.
Pultruded grating can only support weight in the direction of the bearing bars. The bearing bars in Pultruded Grating must traverse from support to support whereas Molded Grating is equally strong in both directions.
Molded Grating panels can be rotated 90 degrees with the same support characteristics.
