The flag poles components are manufactured from aluminum using stainless steel hardware and fasteners to prevent rust and corrosion allowing for years of trouble free service with very little maintenance. These flag poles are installed using a steel foundation tube which includes lightning spike and support plate and considered to be a permanent installation.
