Molded Grating: Mesh Patterns
|
There are two available mesh patterns: Square and Rectangular.
 |
The traditional square mesh pattern offers bi-directional strength, which allows for increased loading capacity compared to rectangular mesh. |
|
 |
The rectangular mesh pattern offers greater one-directional strength than a square mesh pattern. |

Molded Grating: Strength Verses Corrosion Resistance
|
The strength and corrosion resistance of fiberglass grating is determined by the Resin-to-Glass Ratio. The resin component of fiberglass grating provides the corrosion resistance; the glass component provides the grating's strength. Molded fiberglass grating has a higher resin-to-glass ratio than Pultruded Fiberglass Grating, which makes it more corrosion resistant.
The continuous interwoven glass strand construction of molded grating offers a strong bi-directional load capacity. Molded gratings with high resin contents tend to retain a higher percentage of original stiffness over long exposure times. Molded Fiberglass Grating is composed of approximately 65% resin and 35% continuous fiberglass strand for optimum corrosion resistance.
The degree of corrosion resistance for fiberglass is superior to stainless steel, aluminum and galvanized gratings. Molded Fiberglass Grating is low maintenance and will never rust or need to be painted. The non-porous compound found in molded grating helps to eliminate bacterial breeding areas in food applications.

Molded Grating: Surfaces (Standard vs. Grit)
|
Molded Fiberglass Gratings are offered in a concave (meniscus-shaped), grit surface and on some products a smooth surface is an option. The grit surfaces are offered in three types:
· Extra Coarse - Suitable for oily or greasy environments
· Regular - Suitable for most applications
· Fine - Minimal slip resistance
Molded Fiberglass that is ordered with an "Integral Grit" surface offers more slip resistance and durability than the grit types listed above. Integral grit is 3/16 inch deep compared to a the above grit surfaces, which are approximately 1/16 inch deep. Click here for more on Integral molded fiberglass grating.

Molded Grating: Fabrication Features
|
| The unique molded construction allows the grating panels to be easily cut and modified to fit almost any requirement. In areas that require special cuts or areas to be field cut and fabricated, molded grating offers great versatility and will often eliminate the need for additional support for cut edges. When cutting Molded grating, affected areas should have surfaces sealed with catalyzed resin sealant to avoid wicking. |
