Lightning rod connectors for building lightning protection, generally composed of parts such as the lightning rod base, rod body, and lightning termination, with a height range of:0.4 meters to 20 meters. Lightning rods below 12 meters are commonly used for installation on the rooftops and exterior walls of buildings, as well as on the rooftops and sides of metal structures, side or top of cooling towers, top or side of metal tanks, boiler tops or sides, and various other building structures. The rod body is preferably made of steel pipe, while the terminal rod should be made of round steel. After welding, the entire lightning rod should be hot-dip galvanized. The terminal end of the terminal rod should be hemispherical, with a small bending radius of 4.8mm and a large one of 12.7mm. The connection point between steel pipes should have the through-bolts installed before welding with electric weld nuts.
