Zusammenfassung:	A grating system includes a first welded subassembly and a second non-welded subassembly joined to one another. The first subassembly includes spaced elongated bearing bars and spaced elongated cross bars extending transversely to the bearing bars. The second subassembly includes spaced elongated filler bars and spaced elongated cross bars extending transversely to the filler bars. The filler bars extend in the same direction as the bearing bars and are disposed in sets between adjacent bearing bars. The bearing bars include spaced notches in which are received the first subassembly cross bars and the second subassembly cross bars, which are aligned above the first subassembly cross bars. The subassemblies have respective upper surfaces which are flush with one another. The first subassembly is configured to support vehicle traffic and the second subassembly is configured to support pedestrian traffic.
