Pultruded FRP Grating

FRP Grating at Fallbrook Energy Storage north of San Diego, CA

Everyday, more and more people are discovering the benefits of FRP for all kinds of projects. FRP is often the best choice for wet or corrosive environments where steel has rusted out. You’ll find  lots of FRP in waste-water treatment plants, pump stations, mine-sites, cooling towers, cellular antenna shrouds, and waterparks to name a few.

Lighter, Stronger

Pound for pound, FRP is stronger than steel. It won’t rust either so fiberglass grating is the preferred choice where weight is an issue such as marine docks, or entertainment stages. It’s also non-conductive, so it is used extensively in hydro-electric applications.

Molded and Pultruded Grating

We provide both FRP molded grating and FRP pultruded grating. While molded grating is the most cost-effective option, pultruded grating is stronger and better suited for longer spans. Molded grating is made from a square grid pattern using a 3/4″, 1.5″ or 2″ square mesh. It’s also bi-directional so  it’s equally strong in both directions. Pultruded grating is made from a series of parallel bars and can span up to 5 feet depending on the load.

Fiberglass Grating 1.5 Inch Square Mesh

Fiberglass Grating 1.5″ Square Mesh

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.

Typical square mesh pattern of molded FRP grating

Molded FRP Grating

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.

This molded fiberglass grating with square mesh pattern is one of many square mesh patterns available from National Grating.

This molded fiberglass grating with square mesh pattern is one of many square mesh patterns in stock and available for quick delivery from National Grating.


For 1″ inch molded grating, the maximum span is typically 24″. Anything farther apart than 2 feet, as you will need 1-1/2 thick or 2″ thick. Take a look at our Grating Selection Chart to see the various grating options depending on the span.

We stock our molded grating in Dark Gray, Light Gray, Yellow, and Green. Call 1-877-984-7788 for up-to-date pricing and availability for the size and color you need. We have warehouse locations throughout USA and Canada, so we will always quote the closest location to you to minimize freight costs.

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.
