FRP Pultruded 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 fiber/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
Many applications can benefit from fiberglass grating, such as: Sewage treatment, water supply and drainage, chemical petroleum, electric power, paper making, engineering construction, textile printing and dyeing ships.

Benefits of pultruded fiberglass grating:
| Corrosion Resistant |
Can withstand the corrosion of various gas and liquid media such as acids, alkalis, organic solvents and salts. ,According to the requirements of actual use occasions, orthophhthalic, iso-phthalic and vinyl resins can be economically selected as matrix materials. |
| Light quality and high strength: | FRP pultrusion grating is the glass fiber, continuous felt, surface felt and other reinforced materials through resin infiltration heating pultrusion molding. The high glass fiber content (more than 60%) makes the unidirectional specific strength and stiffness quite prominent. |
| Low Maintenance | FRP pultrusion grating is also the color paste blended into all resin production, its bright color, not easy to fade, no paint and self-cleaning effect. |
| Fire Retardant | FRP pultruded grating with oxygen index above 33 and flame propagation rate (according to ASTM E-84 test) <25 are Grade I flame retardant and are approved by the American Classification Society (ABS) |
| Extended Service Life | FRP pultrusion grating is made of high quality resin and glass fiber system to ensure the service life of products in more than 20 years. After exposure to the atmosphere, although the appearance has changed, but 20 years after the intensity can still retain more than 85% |
| Impact and fatigue resistance | FRP pultrusion grating has the same high impact strength as molded grille, allowing repeated bending without permanent deformation; With moderate flexibility, so that long-term work in the above staff feel comfortable. |
