ABSTRACT:
A support pole with enhanced strength along it's base includes an elongated pole member secured to a mounting plate. A majority of the length of the pole member has a uniform cross-section. Slits are cut into each side of the pole member along its lower end. A mandrel is placed into the lower end of the pole and expanded, thereby expanding the lower end of the pole away from the center and creating a larger cross-sectional area at its lower end. The lower end of the pole is secured to the mounting plate. Reinforcing members are welded over the expanded slits and the bottom of the reinforcing member is further welded to the mounting plate. The lower section with a larger cross-sectional area increases the moment of inertia and surface area of the support pole, thereby increasing the strength of the support pole.
