Quality is embedded in every stage of our production process, from raw material control to final inspection. Our ductile iron poles are tested up to three times the maximum permitted working load, with results independently verified by the reference laboratory of a power research institute and cross-checked using finite element analysis software.
Every product line is manufactured in compliance with internationally recognized standards, including ISO 8179, ISO 4179, EN598, ISO 2531, EN545, ISO 4633, ISO 16134, ISO 10804, and ISO 16631, and holds certifications from DVGW, GC-MARK, and MPA NRW.
We back our ductile iron poles with a 15-year guarantee, reflecting our confidence in the durability and corrosion resistance of our products — engineered for a service life exceeding 80 years in buried infrastructure applications.
Our management approach prioritizes continuous testing, standards compliance, and long-term reliability over short-term cost savings, ensuring that every product leaving our facility meets the demands of critical water, wastewater, and energy infrastructure.
