Feautures:
20m decorative lightning tower, roof decorative lightning tower,
decorative lightning tower. The shape style is various, the
appearance is beautiful, the design is novel and unique, widely
applies in each kind of building roof, the square and the community
green space construction and so on. Decorative tower's function
characteristic: The craft tower that my company
develops, the shape is beautiful, the quality is reliable. In the
modern city construction, not only decorate the office building,
and play the building lightning protection grounding, aviation
warning and other effects. It can also raise the height of antenna,
increase the radius of communication service and reduce the blind

design, widely used in various types of building roof, square and
green areas of residential buildings, so that it and the
buildings complement each other, become landmark decorative
buildings in the city. Main functions of decorative lightning
