Traditional excavation shoring relies on heavy steel sheet piles or concrete structures, which not only entail high transportation costs and lengthy installation periods but also tend to cause damage to the surrounding environment. The emergence of plastic-steel sheet piles is sparking a “lightweight revolution” in excavation shoring

Weighing only one-eighth as much as steel sheet piles of the same specifications, plastic-steel sheet piles can be transported and assembled manually without the need for large cranes. In a commercial complex project in the city center, the contractor used plastic-steel sheet piles for temporary excavation shoring. Compared to traditional methods, construction efficiency increased by 40% and costs were reduced by 25%. Their excellent anti-overturning performance and load-bearing capacity successfully withstood the soil pressure on the excavation walls, ensuring the safety of underground structure construction

In addition to temporary shoring, plastic-steel sheet piles can also serve as permanent retaining walls. In mountainous construction projects, they can flexibly adapt to complex terrain; by adjusting the assembly angles, protective structures that conform to the contours of the mountainside can be constructed. Furthermore, the recyclable nature of plastic-steel sheet piles aligns with the principles of green building, reducing the generation of construction waste
