4. If the quality control is strict, the ground should be covered with striped cloth or health care cloth before the steel strand passes through the beam, so as to minimize the dirt and gravel scraped when the anchor cable enters the pipeline. (Many construction units ignore this point)

5. Generally, members larger than 25m are symmetrically tensioned at both ends.
