Flagpole shafts are manufactured in the United States from seamless 6060-T6 aluminum with tensile strength not less than 30,000psi and a yield point of 25,000psi. Shafts in excess of 35′ exposed height are shipped as multiple piece units, then field-assembled with a self aligning internal sleeve assembly (patent pending). All Concord flagpoles are polished to a Deep Luster Finish creating an elegant soft sheen. Other architectural finishes, such as powder coat, clear anodized and Duranodic bronze, are available. In the standard mounting application, Concord flagpoles are produced for the popular ground mount method. In this configuration, the overall shaft length includes the exposed height measurements plus 10% additional that fits into a ground sleeve assembly.
