Metal structural parts such as attics, guttering, railings or cladding can be used as natural components of an air-termination system. If a structure has a steel skeleton construction with a metal roof and facade made of conductive material, these can be used for the external lightning protection system, under certain circumstances.
Sheet metal cladding on the walls or roof of the structure to be protected can be used if the electrical connection between the different parts is permanent. These permanent electrical connections can be made by e.g. brazing, welding, pressing, screwing or riveting, for example. If there is no electrical connection, a supplementary connection must be made for these elements e.g. with bridging braids or bridging cables.
