Available in standard satin finish. While all of our aluminum flagpoles require little maintenance to retain their natural shine, our anodized flagpoles offer an even simpler solution. Our satin brushed finished flagpoles will generally keep clean with the rainfall in most areas, however; because the exterior of the flagpole is aluminum, it will continue to oxidize throughout its lifetime. Special cleaning agents may be required to remove the discoloration caused by this process of oxidation. Our anodized flagpoles do not encounter this problem. The process of anodization actually creates a barrier on the external surface of the aluminum flagpole, thus eliminating the oxidation process. Because the aluminum is not exposed to the elements, it cannot oxidize. The anodized finishes allow you to clean your flagpole with simple soap and water. For this reason, we recommend the purchase of an anodized finish on all of our flagpoles.
