Fiberglass reinforced plastic grating (also known as FRP grating, glass reinforced plastic grating or fiberglass grating) is a composite material manufactured by combining a matrix of resin and fiberglass. Fiberglass grating does not corrode like steel grating and is therefore used in corrosive environments to reduce maintenance costs. It is used in a variety of applications including walkways and overhead platforms. FRP grating is a structural product that can be weight-bearing between spans.

Molded FRP grating is composed of alternating directional layers of continuous glass fiber for strength, with resin to consolidate the fibers and provide the shape and corrosion-resistance. Due to its bidirectional strength, molded grating can tolerate cutouts in the panel to allow pipe or equipment penetrations without requiring additional support around the opening. Molded grating has very high impact tolerance, as well as the highest chemical resistance of any fiberglass grating. It can be made slip-resistant by adding grit to the surface.
Pultruded FRP grating consists of continuous glass strands encased in resin and wrapped in a surfacing veil which protects the fibers and allows resin to saturate the outermost part of the bar as well as penetrate between the glass fibers. This ensures a smooth and corrosion-resistant surface, with a higher glass/resin ratio than molded products. The individual bars are then assembled using cross bars and epoxy to mechanically join the load bars. Pultruded grating has unidirectional strength, with its much higher glass content resulting in a greater span capability than molded products. This product is usually specified in applications requiring larger spans or heavier loading.[1]
FRP/GRP Composite materials are replacing conventional materials and major asset-owners are fostering innovation and steadily increasing the use in so many applications. By combining fibreglass rovings with a thermosetting resin, these are proven to withstand the effects of corrosion and are highly impact resistant, and each day newly found applications are discovered. They meet the same specified load requirements as steel and are more resistant to impact.[2]
Many resin types may be used in pultrusion including polyester, polyurethane, vinylester epoxy, isophthalic polyester, orthophthalic and phenolics.

Fiberglass grating is often used when there are safety concerns due to liquids or oils on the floor and more corrosive environments needing chemical resistance.
Many applications can benefit from fiberglass grating, such as: walkways, platforms, protective shielding, machinery housings, raised floors and stairways.
In addition, Industries that use molded fiberglass grating can include bottling lines, food processing plants, lift stations, commercial aquariums, lube oil facilities, plating shops, beverage canning facilities, chemical plants and pulp and paper plants.

Fiberglass grating is a composite material which is produced by a combination of resin and fiberglass. Fiberglass grating does not corrode or rust as steel grating does and, as such, it finds use in corrosive environments to decrease maintenance costs. It is used in a broad range of applications such as walkways and overhead platforms as it can be weight-bearing between spans.

Fiberglass composite materials are being used in place of traditional materials in many areas with major-asset owners innovating and increasing the application of these materials.
What is Molded Fiberglass Grating?Molded fiberglass grating is made up of alternating directional layers of continuous glass fiber for fortitude. This is in addition to resin, which consolidates fibers and makes up the shape and corrosion-resistance. Because the strength is bidirectional, molded grating can withstand cutouts in the panel for equipment without the need for additional support around the opening.
Molded fiberglass grating has extremely high impact tolerance and has excellent chemical resistance. It is also highly slip resistant, an attribute which can be enhanced by the addition of grit.
What is Pultruded Fiberglass Grating?
Pultruded fiberglass grating is made up of continuous glass strands which are enclosed in resin and wrapped in a surfacing veil to safeguard the fibers whilst allowing resin to saturate the outermost section of the bar and penetrate between glass fibers.
This process means that a smooth and corrosion-resistant surface can be achieved with a favorable glass/resin ratio. Individual bars are assembled with cross bars and epoxy to mechanically fuse the load bars.
Pultruded fiberglass grating possesses unidirectional strength and has much higher glass content than molded fiberglass grating. This means that it has higher span capability and is often used for applications which need heavier loading or larger spans.
Uses of Fiberglass Grating
Fiberglass grating can be used in many different applications, particularly when there are safety concerns because of liquids or oils on the floor as well as in corrosive environments which require chemical resistance.
Some of the applications which are well-suited to fiberglass grating are:
Some industries are well suited to molded fiberglass, such as:
Fiberglass Grating Solutions from Strongwell
At Strongwell, we provide both molded and pultruded fiberglass grating solutions. DURAGRATE® is our molded fiberglass grating offering with a high-quality mesh grating panel. DURAGRATE® is exclusively made in the U.S.A., fire retardant, low in conductivity, light weight, impact resistant, cost effective, and easy to install. This fiberglass grating is fully compatible with FGMC standards.
DURADEK® and DURAGRID® are our high strength pultruded bar grating brands which can be used in a similar way to traditional metal grates of molded fiberglass grating with the addition of inherent pultrusion benefits. This pultruded fiberglass grating works well as a substitute for aluminum or steel gratings where avoiding frequent replacement costs would be beneficial.
DURADEK® is offered in a limited number of colors and configuration whilst strategically producing stock quantities so Strongwell can keep costs at a more comparable price to traditional molded grating. This means it is a more viable, cost-effective alternative without compromising the benefits. DURAGRID® is a fully-customizable grating series when bespoke configurations or performance characteristics are desired.
Pultruded and molded fiberglass grating options can both be provided by Strongwell. If you would like our expert advice on which type would suit your application, contact us today. Alternatively, read our five tips on FRP grating selection for more insights.
