Combining corrosion resistance, long life and a low maintenance design, FRP pultruded grating (Fiberglass pultrusion grating) is superior to conventional metallic gratings. This advanced grating is manufactured with a recessed tie bar configuration and is lightweight and easy to fabricate. Savings on labor and equipment often make the total installed cost of grating comparable to that of steel. This advanced pultruded grating is designed for use in a wide range of industrial applications that require strength and corrosion resistance. Manufactured with a high percentage of glass within the laminate, pultruded grating provides durability, extremely high unidirectional strength and stiffness. Due to its exceptional stiffness, it can be used with confidence where wide support spans are required. For most applications where it is used to replace steel grating, ZJ Composites industrial grating rarely requires additional support. Combining its low cost of installation with low maintenance and long life, ZJ Composites offers a life cycle cost that is significantly lower than that of its metal counterpart.
The ZJ Composites line includes High Load Capacity (HI) grating for up to H20 vehicular loads, industrial grating for standard industrial loads and pedestrian grating for foot traffic.

Corrosion Resistant:
ZJ Composites pultruded fiberglass products are known for their ability to provide corrosion resistance in the harshest environments and chemical exposures.
Slip Resistant:
The integrally applied grit surfaces of ZJ Composites pultruded products have unmatched slip resistance for improved worker safety.
Low Maintenance:
The corrosion resistant properties of FRP grating and other products reduce or eliminate the need for sandblasting, scraping and painting. Products are also easily cleaned with a high pressure washer.
Fire Retardant:
Most ZJ Composites products are engineered to have a flame spread rating of 25 or less, as tested in accordance with ASTM E-84, and meets the self-extinguishing requirements of ASTM D-635.
High Strength to Weight Ratio:
Less than one-half the weight of steel grating, allowing easy removal for access below floor level and installation with no heavy equipment and less manpower.
Electrically & Thermally Non Conductive:
Fiberglass is electrically non conductive for safety and has low thermal conductivity which results in a more comfortable product when physical contact occurs.
Low Install Cost:
Due to ease of fabrication and light weight, FRP pultruded grating eliminates the need for heavy lifting equipment.
Long Service Life:
Fiberglass products provide outstanding durability and corrosion resistance in demanding applications, therefore providing improved product life over traditional materials.
UV Protection:
UV inhibitors in the resin matrix, a synthetic surfacing veil, and grit top surface provide optimum protection from the structural effects of UV weathering. (Phenolic resin grating does not have the UV inhibitor or veil and therefore must be coated for UV protection.
