To provide uniform lighting of areas in all directions, protection of buildings and structures from lightning strikes and from voltage surge in the power supply network. Lightning rod which is immediately exposed to lightning strikes is a steel rod protected from corrosion.
Protection from corrosion by hot galvanizing (ISO 1461). This type of coating is not decorative, but only functional. Corrosion resistance warranty is at least 25 years.
Lightning diverters VGM and VGN represent steel multifaceted masts with lighting equipment and lightning arresters installed on top of them.
VGM and VGN poles have both standard versions designed for standard operating conditions and individual versions which take into account special climatic conditions and order requirements.
Under a special order it is possible to manufacture any standard sizes to be used in wind region I-VII.
For each project support design is individually calculated.
Complete nomenclature of serial products and complete technical data are provided in the Technical Catalog.
