Molded Fiberglass Grate

KORDEK compression-molded Fiberglass Reinforced Plastic (FRP) gratings offer the best available combination of strength,durability and ease of installation. The compression-molded grating system is the only system of its kind in the world. The patented matched-die process exerts over 600-tons of heated force uniformly throughout the entire glass and resin bonding operation. The hydraulic pressure of compression-molding forces glass deep into the resin, creating an extra dense and less porous grating than with open molded grating. The resulting high density KORDEK grating panels provide higher flexural and impact strength and better chemical and UV resistance than any other molded FRP grating. The molded raised studs on the surface of each panel (which are not available on open molded grating), provide the additional advantage of a non-skid surface.
The strength of KORDEK results from the unique way the continuous strands of reinforcing glass are woven throughout the grating (each panel contains more than 60% glass). The power molding process of KORDEK employs twice as much reinforcing glass as is found in open molded FRP gratings. As a result, KORDEK gratings are up to twice as strong as open-molded gratings, and can be verified by comparing load/deflection data. Greater strength in less thickness allows for fewer support members for given deflection, which reduces material cost and translates to savings for our customers. Compression molding makes KORDEK a stronger more durable grating with an extra measure of corrosion and UV resistance that surpasses open molded gratings under typical grating installations.
