Interlocked steel grating (also known as interlocking / dovetail grating) is assembled by slotting and interlocking flat bars in two directions, without twisted cross bars. It forms neat square apertures with dense uniform gaps and high rigidity, preventing small objects from falling through. Used for municipal trench covers, viewing platforms, building ceilings, equipment protective grilles and exhibition halls。
