These poles are preferred to the regular flag poles which are made of aluminum and if you buy one you will understand why.
Most of the metal poles are resistant but not as resistant as the fiberglass ones. Besides being very strong and surviving almost any weather conditions, they have other advantages as well.
They are resistant to sun and moisture as well, they won't get rusty like some of the metal flag poles do. They are also very resistant against corrosion, which can be a real trouble if the flag pole is installed near the sea.
The best thing about them is that they don't need maintenance. While most of the other flag poles need to be checked and changed from time to time, fiberglass poles will be just fine and won't cause you any extra trouble. They are also very silent, they don't make any noise. If you have ever lived close to a flag pole you know how annoyingly loud metal flag poles can be.
A lot of people decide to order such fag poles also because of their lightweight. Metal flag poles can be extremely heavy, especially the tall ones, and therefore they are hard to ship and to install, while fiberglass ones don't represent such a problem. Metal flag poles can also be dangerous because they conduct electricity, and if there is a storm they can represent real dangers for those around. If you want to be cautions, buy a fiberglass pole instead of one made of metal.
