1/ Description
The Heavy Duty Walkway Absorber provides a path to transmit and receive areas that will support heavier loads by
incorporating a high strength, load bearing grid into the walkway. This grid enables the walkway to support much
heavier loads than standard walkway. Custom sizes and shapes can also be provided, including much larger sizes
than standard walkway.
