steel sheet piles are widely used in many fields such as foundation pit support, bank reinforcement, seawall protection, wharf construction and underground engineering. Due to its excellent carrying capacity, it can effectively cope with soil pressure and water pressure. The manufacturing cost of hot-rolled steel sheet pile is relatively low, and it can be reused, and has good economy. At the same time, the steel can be recycled, in line with the concept of sustainable development. Although the hot-rolled steel sheet pile itself has a certain durability, in some corrosive environments, anti-corrosion treatment such as coating and hot-dip galvanizing is often used to further extend the service life.
