Flagpoles changed a lot since 1876 when Americans first flew the flag. Flagpoles used to be made only of wood prior to the industrial revolution. While there are some US companies that specialize in Rustic venues for flagpoles, others still use this method. However, today’s flagpole manufacturers make flagpoles with more durable materials, go to my site.
Carpenters would use their hands to cut straight trees for the first flagpoles. These trees would then need to be shaped using whittling or sanding, until they reach a smooth finish. The wood was preserved by using animal fat as a preservative. The whole pole was then rubbed with the fat over several days. These poles are durable and can last for 50 years if taken care of properly. These flagpoles looked great, but they could eventually become rotted at their base. The flagpole can also serve as a lightening conductor. The lightening can cause them to become brittle or burn.
The masts of ships and steel tubes were used to create flagpoles in the 20th century. The use of old wooden poles, which had been processed, became less common. After 1929’s stock market crash, steel shafts became popular to pile drive large ships and support cargo booms. This was the inspiration for many flagpole manufacturers. This smooth and tapered flagpole made of steel was the dominant type for more than twenty years. The most popular version of the flagpole was the next. Aluminum was the best choice for flagpoles. The flagpole market’s most important component is today aluminum.
Aluminum is known for its many characteristics. These properties allow for aluminum to undergo molecular transformations, which enable it to produce different products and uses. 6063 is the most commonly used aluminum alloy to make flagpoles. These aluminum alloy flagpoles can either be extruded pipes or tubes. All must comply with ASTM B241, “Aluminum Alloy Sealing Tube” and Seamless extruded Tube. This alloy has a T6 temper rating, which is the hardest. The majority of these poles have been heat-treated. This temper rating provides a fantastic level of low stress at just 25Kilograms per square inch. Tubes can also be designed at 18,000 Kilograms per square inch.
