A tapered metal pole has at least three ribs. Each rib has two parallel spaced apart walls. The inner edges of the walls of one rib will be welded to the inner edges of the walls of another rib. The walls of adjacent ribs will be at an angle relative to each other. An outer plate extends between the outer edges of each wall. The walls taper in width from a lower end to an upper end. Each of the walls of the ribs intersect with the walls of an adjacent rib at an angle.
