Leveraging polymer-modified composite technology and structural steel reinforcement processes, we have independently developed a new generation of high-strength plastic-steel sheet piles that completely overcome the application limitations of traditional steel sheet piles and concrete piles, providing a brand-new support solution for the green infrastructure industry.

We have innovatively adopted a composite structure featuring an embedded steel core encased in a polymer outer layer. Through precision manufacturing processes that integrate the core strengths of both materials, our product combines the high load-bearing capacity of steel with the corrosion resistance and stability of modified plastic, fundamentally addressing the industry’s pain points associated with traditional support materials—such as insufficient strength, susceptibility to corrosion, short service life, and high pollution levels.

We have optimized the design of the high-moment-of-inertia cross-section to precisely distribute lateral soil pressure, significantly enhancing the sheet’s resistance to bending, impact, and lateral deflection, and enabling it to easily adapt to complex construction conditions such as soft soil foundations and high-water-table strata.

We use an integrated extrusion molding process to mass-produce plastic-steel sheet piles, strictly controlling product precision to create a precision interlocking structure. Once assembled, the sheet piles form a seamless, monolithic retaining wall, creating a highly effective water-stopping barrier. This structure effectively blocks groundwater seepage pathways, mitigating engineering risks such as seepage in embankments, excavation pit leakage, and soil collapse, with waterproofing and seepage prevention performance far surpassing that of traditional methods.

We have significantly reduced the product’s weight; for the same support specifications, our plastic-steel sheet piles weigh only one-third as much as traditional steel sheet piles, greatly simplifying transportation, hoisting, and pile driving operations. Construction teams can complete all operations using small vibratory hammers and mini excavators, eliminating the need for large, heavy-duty equipment. This makes the product perfectly suited for constrained environments such as narrow urban work sites and waterfront construction areas.

We adhere to a green, low-carbon production philosophy by selecting eco-friendly, non-toxic raw materials and incorporating compliant recycled plastic pellets. The entire production process involves no high-temperature calcination and produces no exhaust gases or waste residue, significantly reducing carbon emissions per unit of project. We have eliminated the drawbacks of traditional steel—such as frequent rust removal and anti-corrosion treatments—and concrete’s heavy consumption of sand and gravel resources. The product’s outer layer of polymer material provides long-term resistance to corrosion from seawater, acidic and alkaline soils, and chemical wastewater, ensuring 50 years of service life without requiring specialized maintenance.

We implement a full-lifecycle recycling model: after temporary projects are completed, the products can be fully removed, recycled, refurbished, and reused; end-of-life components can be melted down and remanufactured, thoroughly reducing the generation of construction and infrastructure waste. Currently, we have widely applied this product in scenarios such as municipal excavation pits, river channel rehabilitation, highway slopes, and seawall flood control. With its robust performance and eco-friendly attributes, it continues to drive the low-carbon transition of the infrastructure industry.
