FIBREGLASS GRATING

Fibreglass 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 fibreglass.  It does not corrode like steel grating and provides long term use while reducing maintenance costs. 

Fibreglass grating is often used when there are safety concerns due to liquids or oils on the floor, and in more corrosive environments in need of stronger chemical resistance. It can be used in many different applications such as walkways, platforms, protective shielding, machinery housings, raised floors and stairways.

Industries that use Fiberglass grating can include food processing plants, lift stations, commercial aquariums, lube oil facilities, plating shops, beverage canning facilities, chemical plants, and pulp and paper plants.

Molded 

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.

Molded FRP grating is available in square or rectangular patterns and can range in thickness from ½” to 2”. The square pattern ranges from ¾” x ¾” to 2” x 2”. Rectangular pattern has sizes from 1” x 4” to 1 ½” x 6”. It is available in a variety of colors, with the most common being yellow, dark and light gray, green, and red. Material can be supplied in panels ranging from 3’ x 8’ to 5’ x 12’ or supplied made to size to fit a specific project specification.

Pultruded 

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.

Pultruded FRP grating is available in I-Bar or T-Bar and can range in thickness from 1” to 2”. There are various spacings available depending on the requirement of the project. It is available in a variety of colors, with the most common being yellow, dark and light gray, green, and red. Material can be supplied in panels ranging from 3’ to 5’ wide x 8’ up to 24’ long. Material can also be supplied fabricated to size to fit a specific project specification.
