摘要: A grid plate of plastic material, with a rough, slippage-impairing top side and a rib-reinforced bottom side. The individual grid plates are kept together by a lockable, but again disconnectable, plug-in connection. The grid plates serve as fastening elements for parking places, road embankments, road ramps, and the like.
