Because a single pole failure can be catastrophic, it is essential for municipalities, commercial property owners and other individuals responsible for public safety to routinely retain the services of NACE-certified inspectors and failure analysts. Matergenics provides structural condition assessment, integrity inspection and corrosion risk assessment services for aging infrastructure including monopoles and high-mast lighting towers, in addition to a wide range of similarly critical structures.
Light POLE, CONDITION ASSESSMENT and INSPECTIONS
Matergenics certified engineers and technicians have many years of experience in condition assessment, corrosion risk assessment and corrosion mitigation for these type of structures.
Cracking of Traffic and Light Poles can result from wind loading due to improper design. Manufacturing defects and improper paint coatings result in early failure in service. Corrosion on poles is directly related to the atmospheric and soil conditions present for the unique location of a given pole structure, as well as to the materials of manufacturing and the quality of these materials.
1-Internal corrosion due to the presence or entrapment of corrosive water (electrolyte)
2-External corrosion due to corrosive atmospheric and environmental conditions
3-Fatigue of Traffic and Light Poles due to wind loading and inadequate design
4-Manufacturing defects and improper paint coating selection and application
5-Little or no maintenance in corrosive environment
6-Accumulation of debris and soil under base plate
Accelerated Corrosion, Perforation and Degradation due to corrosive environment and aging.

Analysis Root Cause Determination
Failure analysis is the method that is used to determine the root cause of failure when light poles, components, assets, or systems fail to meet performance expectations. The findings of a root cause failure analysis provide decision makers with the tools they need for remedial actions and preventative measures to be taken.
At Matergenics, our diverse engineering team of Ph.D. level scientists, professional engineers and NACE certified engineers (materials, metallurgical, corrosion, mechanical), and chemists can assist you with your root cause failure analysis needs. Areas of specialization include the steel making, manufacturing, aerospace, automotive, oil and gas, electric power, telecommunication, and wind tower industries.
Although Matergentics materials testing work is vital to its clients, it is rarely seen by the public. Here are some examples of recent projects in which our experienced Matergentics engineering team provided the timely, competent, customer-oriented engineering analysis that made the difference.
1-Cracking at base plate of light poles (see the above pictures) due to improper design, fatigue and dynamic wind loading
2-Accelerated Corrosion due to deicing salt exposure in North East
3-Coating delamination due to improper surface preparation of the pole
Recent articles in Materials Performance, the official trade publication of NACE International, were co-authored by Dr. Zee (M. Zamanzadeh, PhD, NACE and ASM Fellow), Director of Matergenics’ Corrosion and Materials Engineering, and Lana Gilpin-Jackson, Specialist Engineer in Lines Strategy and Standards for BC Hydro. Packed with useful information, the article educates and informs the reader on many important factors related to the life of galvanized steel structures and corrosion risk assessment. The content of the two-part article is pertinent to anyone responsible for electric reliability and grid asset management at electric utilities.

Dr. Mehrooz Zamanzadah or Dr. Zee as he is known to the pole industry has been for many years a valued consultant to Valmont Industries. His new company, Matergenics, continues Dr. Zee’s legacy to provide expert analysis and solutions to extending the life of the infrastructure through corrosion mitigations and failure analysis.
I have had the honor or working with Dr. Zee professionally in committee work and in the pole business for many years and Valmont has benefitted greatly from our association. I look forward to continuing working with Dr. Zee and Matergenics.
