While capitalizingon some of the traditional benefits of pultruded gratingproducts - high strength, corrosion resistance, slipresistance, fire retardancy, non conductivity and lowmaintenance - this pultruded FRP product has beenengineered to carry the forklift and tractor trailer loadsthat traditional pultruded FRP grating products are unableto support.47%, and 58% open surface area 37%,Available in 1”, 1-1/2", 2", 2-1/2", and 3" depthsfor up to H20 loads in all five depths RatedFlame spread rating of 25 or less (when tested in accordance with ASTM E-84) and a Class 1 Fire Rating HI37 Grating is ADA Compliantpanels consist of: Standard--Fire retardant vinyl ester resin system--Dark gray in color--Aluminum oxide grit top surfaceEach HI grating is specially engineered to meet specific requirements. Contact the Fibergrate engineering team todetermine which grating offers the best solution for your high load needs.

Load is carried by the grating load bars immediately under wheel two additionalload bars, one on each side of wheel.2. Allowable Span is based on a 0.25" maximum deflection and a Factor of Safetyof 3.0. Other criteria may be required by certain construction codes. Check coderequirements to determine design critieria.3. Allowable span is strongly dependent on wheel width and vehicle weight/loadcapacity.
