The American Iron and
Steel Institute (AISI) estimates that approximately 185 million utility poles
are in service in North America, and most of them are made from wood. When
utility poles need to be replaced or a new distribution line set up, utility managers
consider factors such as cost and reliability. But increasingly they are also
considering the impact of the material on the environment and reviewing their
options. By Mark Thimons, director, construction sustainability, Steel Market
Development Institute, a business unit of the American Iron & Steel
Institute
