Flagpoles underwent many significant full article changes since 1776 when the United States began flying their flags. Even before the industrial revolution, flagpoles were entirely made from wood. Even though there are still some Rustic companies operating in the US, they continue to use this method. However, flagpole makers today use durable materials that last longer.

For the first flagpoles to be built, Carpenters would cut straight trees by hand. The next step was to shape the trees by handsawing straight trees. To ensure that the pole was completely saturated with fat, it was scrubbed for several hours using animal fat. The poles are durable enough to last 50 years if they are maintained well by an experienced craftsman. These flagpoles look great but are easily damaged by ground rot.

The wooden processed poles were replaced by steel tubes as early as 1893. After 1929’s stock market crash, steel shafts became the main inspiration for many flagpole producers. This type of smooth-edged and tapered steel pole was the dominant in the industry for more than 20 years. These are the most popular of all the inspirations for the flagpole. Aluminum was the latest material to be used in flagpole manufacturing. Aluminum has taken over flagpole manufacturing.

Aluminum’s many distinctive features allow it to be changed at the molecular stage, creating new products for different uses. 6063 is the most popular aluminum alloy used for manufacturing flagpoles. This aluminum alloy is either extruded or tube formed. It must conform to ASTM B241, Aluminum Alloy Stemless Pipe and Seamless Tub. These poles are typically hardened or aged using heat treatment to attain a temperature rating of T6. This is the hardest form. This temper rating provides an incredible level of minimization at 25,000 lbs per square inch, and an acceptable design stress for tubes at 18,000 lbs/square inch.
