We are researching and developing techniques to strengthen the reliability and environmental adaptation of telecommunication facilities in order to increase their lifetime. This article introduces examples of techniques to determine the degradation of coatings on telecommunication steel towers. An application to lightning damage prediction is also introduced as a risk-based facility maintenance strategy to evaluate the need for maintenance depending on the degree of risk.
