In ecological water conservancy and comprehensive water environment management projects, traditional steel and concrete slope protection structures are prone to issues such as corrosion, salt leaching, alkali efflorescence, aging, and spalling. Not only do these structures lack structural stability, but they also pollute water bodies and damage aquatic ecosystems. As a new type of green building material, zero-pollution polymer-coated steel sheet piles combine structural performance with ecological benefits, making them suitable for a wide range of green water conservancy construction scenarios.
The product features a fully encapsulated, co-extruded structure combining modified PVC with a steel core, with no exposed metal and produced without harmful additives. Its physical and chemical properties are stable; even after long-term immersion in freshwater or saline-alkaline water bodies, no harmful substances leach out. It does not alter water quality, poses no harm to aquatic life, and ensures zero pollution during both construction and use. The outer modified protective layer is resistant to acids and alkalis, aging, and scouring. It can withstand complex conditions such as alternating tidal wet and dry cycles and tidal flat corrosion. With high durability, it effectively reduces secondary pollution caused by the replacement of building materials.
These profiles combine the high strength of a steel core with the high toughness of polymer materials. Their self-locking tongue-and-groove joints ensure a tight fit, providing excellent leak-proof slope stabilization and resistance to lateral pressure. They can accommodate settlement on soft foundations, thereby preventing cracking and leakage. Utilizing a modular construction approach, it minimizes ecological disturbance, generates no construction waste, and is recyclable and reusable. It is low-carbon and energy-efficient, making it widely applicable to water conservancy projects such as ecological waterways, landscape water systems, embankment reinforcement, and aquaculture pond linings. It is the preferred eco-friendly building material for ecological water conservancy construction.
