发明名称 Grating system with enhanced see-through characteristics
摘要 A grating system provides enhanced see through characteristics and typically includes longitudinal deep bars, axial crossbars, axial filler bars between the crossbars and longitudinal joining bars which join the crossbars and filler bars to one another. The deep bars are part of a first subassembly and the other bars are part of a second subassembly which may be lowered to join the two subassemblies to one another. The crossbars and filler bars are typically seated on the deep bars. The joining bars are typically above and aligned with the deep bars. The upper surfaces of the crossbars and filler bars are usually substantially flush with one another. The grating system is configured to support vehicular and pedestrian traffic.
