ABSTRACT:
A pole construction having a generally telescoping configuration between its ends and the method of forming such a pole are disclosed. The pole is formed of longitudinally axially aligned cylindrical structural steel tubes. Each section of tube is of a uniform outer diameter and the respective sections progressively decrease in outer diameter. One end section of a larger tube overlaps the end section of the next smaller tube. An annular body of a non-metallic non-shrinking settable material such as concrete fills the space between the overlapping end sections of the tubes and rigidly secures the overlapping tubes to each other.
