Telescoping flagpoles are constructed from aluminum tubes with different diameters. They slide between each another to make them telescoping. Each section of flag is raised, then locked in place. Telescoping flagpoles don’t need ropes in windy weather. They can be built in heights of 6 to 30 feet. To preserve strength-toheight ratios, telescoping flagpoles can easily be tapered. They are however less strong than single-piece ones, check the original site.
When selecting a Telescoping Pole you need to consider three factors: tubing diameter (or locking system), spring assist (or spring support), and spring help (or spring assist).
The strongest flagpoles have the largest ratio of height and diameter. Telescoping flagpoles which have the longest diameters have the highest strength. Compare flagpoles with the same height by looking for the longest length of tubing. Although wall thickness and pole diameter have some influence on strength, they are not as significant as pole diameter.
There will be many locking mechanisms, each manufacturer having its own patent. Look out for systems that are self-indexing or self-locking. Each section locks automatically into its respective locking position when raised. The locking system should not depend on expansion or friction. You want to avoid bad locks by choosing a locking mechanism that has few moving parts.
A spring support system is vital for manufacturers. Spring assist systems make it easier to assemble smaller flagpoles. Spring assist is necessary for flagpoles that are more than twenty feet tall. The pole weight can vary between twelve and twenty-five pounds.
