DURADEK® Pultruded Fiberglass Gratings are corrosion resistant, slip resistant and typically stocked in a fire retardant polyester resin. The I-bar shaped configuration with 6 inch cross bar spacing is the most popular and provides maximum flexibility in design. We offer three series choices of bearing bar spacings – 1 inch (MS I-4000), 1.50 inch (MS I-6000) and 1.71 inch (MS I-6515 with 8 inch cross bars). This measurement is the center to center of the bar spacing between each bearing bar. Grating panels are available from stock in bar heights of 1 or 1-1/2 inch, in a variety of colors, resins and spacings. Other sizes are available by special order.
