Flagpoles complementing commercial buildings can be found in sizes 20 feet and upward. Once again the size of the building and grounds are the deciding and most important factors. For office buildings flagpoles, 40 to 60 feet in height add a final corporate statement. Remember, however, some buildings will look just as elegant with poles only 25 feet high. Many companies will use two poles and fly the US and state flag. Another option is to use three poles and fly the US, state, and corporate flag or banner. Flagpoles can also be used at entrances or gateways or along drives leading up to corporate headquarters.
