Power poles are a vital part in delivering electricity from the main generators to your home. There are three common types of power poles used in America, depending on what size and strength is required in the particular area where the pole will be erected.
they are hollow and much lighter than wooden poles -- this makes installation much easier, less time consuming; thus cheaper.
Steel poles are generally stronger dependent on the grade and quality of the steel which has been used.
