High Load Capacity Grating
Molded High Load Capacity (HLC) grating is yet another product in the arsenal of engineered fiberglass reinforced plastic (FRP) solutions by Grating Pacific. While capitalizing on most of the traditional benefits of molded grating products - high strength, corrosion resistance, fire retardancy, nonconductivity and low maintenance - this specially manufactured molded FRP product has been engineered to carry the forklift loads that traditional molded FRP grating products are unable to support.
With a 48% open surface area, Fibergrates molded HLC grating is available in a 6' x 4' panel with depths of 1-1/2" and 2" and comes standard in a fire-retardant vinyl ester resin system, dark gray in color, with a smooth surface. Fibergrates molded HLC grating merits an ASTM E-84 flame spread rating of 25 or less and a Class 1 Fire Rating.

Allowable Spans for Vehicular Loads
- Load is carried by the grating load bars immediate under wheel + four additional load bars adjacent to wheel.
- Allowable Span is based on a 0.25" maximum deflection and a Factor of Safety of 3.0. Other criteria may be required by certain construction codes. Check code requirements to determine design criteria.
- ALLOWABLE SPAN IS STRONGLY DEPENDENT ON WHEEL WIDTH AND VEHICLE WEIGHT/LOAD CAPACITY. If your application varies from the values given on this table, contact Grating Pacific for application assistance.
- Load based on the AASHTO Standard Truck Load as defined in AASHTO LRFD Bridge Design Specifications, 2nd Ed. This does not imply that the
allowable span meets the deflection requirements of this specification.
