1. High strength prestressing steel strands are wrapped with spiral wire, and are locked into tension plates at each end of the mold.
2. The specially formulated high strength concrete is placed into the bottom half of the mold.
3. The mold is bolted closed, the strand is prestressed, and then the mold is spun at a high rate. The centrifugal force compresses the concrete against the inner wall of the mold.
4. The finished pole has a hollow center, and is the most dense, least permeable, strongest concrete man can make.
