  1. Constructed of steel not less than 4 inches in diameter and concrete filled
  2. Spaced not more than 4 feet between posts on center
  3. Set not less than 3 feet deep in a concrete footing of not less than a 15 inch diameter
  4. Set with the top of the posts not less than 3 feet above ground
