One of the most popular types of Fiberglass Grating we sell is Molded grating with a 1.5″ x 1.5″ Square mesh pattern. With 1/4″ inch bearing bars, the checkerboard 1-1/2″ square mesh pattern creates a 1-1/4″ inch square opening which equals approximately 70% open area.

Molded Grating comes in sizes 1″, 1.5″ or 2″ Deep. The most common panel sizes are 3′ x 10, 4′ x 8′, 4′ x 12′ and 5′ x 10′. The larger the span between the supports under the grating, the farther the span, and the stronger and thicker the grating has to be.

If you need to cut the FRP grating sheets down to smaller sizes, you can easily cut the fiberglass panels using any saw that you would normally use to cut wood. You can use a skill saw, jig saw, table saw, or reciprocating saw. They key is to use a diamond tip blade. If you try to cut FRP with a regular blade, it will dull far too quickly. Check out our video on How to Cut FRP.

Fiberglass grating will never rust, so it is great for corrosive environments such as as chemical plants, oil and gas, and waste-water treatment facilities. The gritted surface on molded grating provides excellent traction for slippery walkways.

Fiberglass stairs and railing is used instead of steel in swimming pools and water-parks where Chlorine is constantly flowing on the the stairs and decks. We have pultruded fiberglass pool grating for these applications where bare feet walk on the grating, not work boots.
