Amman in Jordan holds the unsupported highest flag pole for sale. The massive carbon steel pole is 416 feet tall and weighs in at 190,000. A flagpole that is this big requires a foundation of immense weight – up to 600 tons. The foundation is bolted to by 36 carbon steel bolts. It can withstand wind speeds up to ninety mph with the flag attached. Two years of design and construction were required, and many major corporations cooperated to make it possible.
While your own flagpole project is not as difficult, the engineering concepts are identical.
You must first decide on the height of the flagpole and the size for your flag. The flag’s length should be approximately 25-40% of the pole’s height.
A commercial flagpole typically stands between thirty and thirty-five feet high. You can make a statement by going shorter if you only want to decorate your front yard. A residential flagpole is usually placed in the 20- to 25-foot range on a home with one or two stories.
The second major decision is which material the pole should be made from. Flagpoles made of aluminum and fiberglass have the best durability. However, they are also available in bronze and carbon steel. Wood is attractive but is not the strongest material. Wallmounted flags are a preferred option. Fiberglass and bronze can be made in almost any color you want. For larger flagpoles, stainless steel and carbon are often reserved.
