Because the density of the metal plate is very different from the density of the cement pile, and the pattern we designed has 8 reinforcement bars, which greatly increases its overall strength. We have done a simple experiment. The single thickness is 1.5mm, 2.4 meters. Long, when testing its bending strength, it was found that 435kg was needed to bend it, and when we installed the poles, the strength of the vegetation and the connection of each pole will be greatly enhanced due to the downward force of the vegetation. In addition to the fixing of the head and side piles of our two, and the tightening force of the steel wire, it can be concluded that its strength is sufficient for application in the fruit tree planting industry.
