We use eco-friendly polymer composite materials to manufacture high-strength plastic-steel sheet piles through a high-temperature, high-pressure one-piece molding process. This material effectively combines the corrosion resistance of plastic with the mechanical strength of steel, achieving a tensile strength exceeding 40 MPa and a flexural strength exceeding 60 MPa. It is capable of withstanding flood impacts, soil compression, and erosion from acidic or alkaline water. We design sections with high moments of inertia and C-T type interlocking joints, ensuring the sheet piles interlock tightly to form a continuous retaining structure, significantly enhancing the overall stability and lateral resistance of the bank protection

In water environment management, plastic-steel sheet piles actively fulfill multiple ecological functions. We incorporate ecological openings and permeable structures into the sheet piles to establish circulation pathways between groundwater and surface water, thereby preventing piping and soil erosion. We utilize these ecological openings to cultivate aquatic plants, actively creating habitats and spawning grounds for fish, shrimp, and other organisms, and rapidly restoring aquatic biodiversity. The material itself contains no harmful substances such as lead or plasticizers, allowing us to eliminate secondary pollution at the source and ensure the ecological safety of water quality and soil

During construction, plastic-steel sheet piles actively streamline processes and improve efficiency. We eliminate the need for cofferdams and large-scale land acquisition, instead using modular assembly and small-scale equipment for pile driving, achieving construction speeds 5 to 10 times faster than traditional methods. We proactively reduce transportation and labor costs while minimizing construction disturbances, making river management more efficient and environmentally friendlyHigh-strength plastic-steel sheet piles effectively balance structural safety, ecological restoration, and long-term maintenance. We regard them as the preferred solution for ecological bank protection, continuously contributing to improved water quality and the healthy development of aquatic ecosystems
