DeltaGrateTM Molded Grating 





DELTAGRATETM High Strength Molded Grating is a one piece, high strength, low weight, corrosion resistant floor grating.  The grating is manufactured with a proprietary method of introducing glass to the mold that allows the grating to have a slightly higher glass to resin ratio than other manufacturers.  DeltaGrate High Strength Molded Grating is on average 15% to 30% stiffer than other open-top molded gratings.

DELTAGRATETM High Strength Molded Grating is manufactured in our  ISO 9001 Certified state of the art, new manufacturing plant.
