Molded Fiberglass Grating was developed much earlier than pultruded grating, it is widely used and performs well in many applications. Molded fiberglass grating has equal strength in both directions and is made with square or rectangular grid patterns.
Molded Fiberglass Grating is manufactured by interlacing pre-wetted glass reinforcing strands in a liquid resin matrix in a mold. Once the resin matrix has cured, the molded grid is removed from the mold. The one piece construction insures that all glass is impregnated with resin.
Strength: Square mesh construction offers bi-directional strength. This construction allows for increased loading versatility when compared to Rectangular mesh. Also, the uniform placement of the continuous glass strands during construction provides superior strength.
Corrosion Resistance: Molded Fiberglass Grating should be used within extreme corrosive environments.
Fabrication Features: In areas that require circular cuts or areas to be field cut and fabricated, Molded square mesh grating offers great versatility and often will not need additional support for cut edges. Special leg pedestals easily create elevated floor systems. The pedestal flooring system helps compensate for an uneven sub floor or slope.
Safety Surface: Molded Grating can be made with a Skid resistant concave surface. A grit surface is also available to provide surer footing for worker safety, while its non-porous qualities help eliminate bacterial breeding areas in food applications.
