A flag pole is a shaft or a pole on which a flag is and can be displayed. Flag poles can be made of wood or metal. Flag poles use a cord which is looped around a pulley at the top of the pole to raise a flag. Very high flagpoles involve more intricate support structure than a simple pole, such as guy wires, or it needs to be built as a mast. Flagpoles can be designed in one piece with a taper or can be made from multiple pieces to make them able to expand.
