Reinforced concrete poles type ZN comply with all requirements of the manufacturing quality control system, described in Annexe ZA to the PN-EN12843:2008 standard.

After the modernization in 2005, the dimensions of the reinforced concrete poles and the placement and diameters of the mounting holes do not differ from the poles previously produced and commonly used in Poland. Our ZN poles are produced from concrete class C35/45 (in accordance with the PN-EN 2006-1 standard), which guarantees that they have a lifespan of 50 years.
