In manufacturing, ESD floor tiles are loaded with conductive elements—such as carbon, graphite or metal-coated particles—that provide electrical conductivity.
Static-control floors are installed over a conductive underlayment, such as copper foils or carbon-loaded adhesive, forming a conductive ground plane.
The conductive ground plane electrically unifies all the floor tiles in the contiguously installed space.
Static flows across the ground plane to copper grounding strips, connected to an electrical outlet or an earth ground such as a steel I-beam or a grounding rod. This electrical connection allows static to complete its circuit and flow safely to ground.
The conductive elements in the flooring material draw static downward, away from people, furnishings and equipment, and conduct static electricity safely to ground.
