The 718 Plastic-Steel Sheet Pile is a new type of eco-friendly polymer composite support profile, manufactured through co-extrusion using modified PVC raw materials. It features a standard width of 718 mm, an integrated rib structure, and interlocking watertight joints. The product’s scientific structural design ensures excellent flexural strength. When joined together, the panels form a complete, sealed retaining wall that is structurally stable and highly impermeable, making it suitable for various small- and medium-scale retaining and waterproofing projects.
This product offers outstanding core advantages: it is lightweight, weighing only one-eighth as much as traditional steel sheet piles; construction requires no heavy machinery; installation and assembly are convenient; it can be cut on-site to accommodate complex conditions such as curves and corners; and it offers high construction efficiency while being recyclable and reusable. Additionally, the material is resistant to acids and alkalis, withstands seawater corrosion, and is rust- and mildew-free. It offers exceptional weather resistance, with a service life of up to 50 years and requires no maintenance. It is environmentally friendly and non-polluting, posing no risk of soil or water contamination.
The 718 plastic-steel sheet pile has a wide range of applications. It is primarily used in projects such as ecological riverbank protection, slope stabilization for ponds and artificial lakes, coastal tidal flat cofferdams, flood control and water retention, temporary shoring for municipal excavation pits and utility trenches, and impermeable barriers for landfills and chemical sites. It is a cost-effective, environmentally friendly building material that serves as an alternative to traditional steel sheet piles and concrete retaining walls.
