Abstract
Structural components of a barrier, including posts, rails and pickets, are formed from a conductive substrate that is encased in a corrosion-resistant nonconductive coating. These structural components are assembled by aligning fastener openings in a pair of components, and joining the paired components with a conductive bolt. The shank of the bolt has an enlarged section of peripheral longitudinal ridges that forms an interference fit within each of the aligned fastener openings. Forming this interference fit abrades away the nonconductive coating within the openings, and allows the shank to form a conductive link between the joined structural components.
