3. Towers and masts constructed from angle material have a much higher wind load than the more sophisticated triangular round member tower. A triangular round member tower is much more aerodynamic and therefore has lower wind resistance.

4. Because of the higher wind load on the structural members, more reinforcing pieces are necessary, and therefore the structure when completed has many more components and connections than a triangular tower.

5. A square tower with all of this extra material, is no stronger than a triangular tower designed for a similar load. There are international standards developed for tower design such as ANSI/TIA/EIA-222-F-1996 that govern proper tower/mast design for the communications industry.

6. As a result of the square angle design, there is more labor involved to assemble the material, more possibilities of pieces not fitting, more connections to loosen and maintain.

7. Triangular towers however are lighter in weight thus saving freight costs, and are constructed of fewer pieces. This is possible because of the higher strength steels that are currently available for the more high-tech tower/mast designs.
