History Of Flagpole

By Barbara Roland


Flagpoles are metal piping with thick enough walls (generally 1/4 inch thick or more) designed to withstand the wind load a flag exerts on the pole during high-wind weather conditions. Galvanized pipe is well-suited to such an application due to its resistance to the formation of rust, which could weaken the metal. Due to this resistance to rust, such pipe can be used as a permanent mast for flying a flag, where untreated steel pipe must be removed periodically and replaced with new pipe to replace a rusty, corroded section.

Lay the galvanized pipe on the ground. Measure 1 foot from one end of the pipe (the top) and mark where the hole is to be drilled to secure the top bolt-on pulley assembly. In like manner, measure 5 feet from the other end and mark where the hole is to be drilled to secure the bottom bolt-on pulley assembly. Make sure the bolt-hole markings on the top and the bottom are lined up as perfectly as possible.

Mix concrete in a separate container per manufacturer's instructions. Fill your bucket up 2 inches with the concrete and allow it to sit for a short time. Place the wrapped end of the PVC pipe into the 2 inches of concrete. Use your level to make sure your pipe is straight.

Bolt the pulleys onto the pipe with an appropriate wrench set, placing a lock washer and nut on each. Tighten until hand-tight, then tighten further until the nuts cannot be turned anymore. Use caution so the bolts aren't stripped while tightening.

Allow the concrete to dry overnight. Take the pipe out of the concrete (it should come out easily due to the petroleum jelly. If you want, you can paint your pipe a different color to give it a more elegant look. Allow the paint to dry before putting the pipe back into the concrete. The pipe should fit perfectly in the concrete.

To raise or lower a flag, a person would attach the flag to the hooks and simply pull the rope until the flag reached the desired height. He would then tie the excess rope onto the pole's cleats. A person could raise the flag and be proud of his or her country. The Flag Company Inc specialized in flag and flagpole designs offered a special edition of flagpoles to memorize the history of flagpole making for the future.
