Steel-plastic sheet piles, as a structural material, primarily consist of specialized steel plates and plastic composite materials. They combine the strength of steel with the corrosion resistance of plastic, featuring light weight, easy installation, and excellent anti-corrosion properties. Robust, stable, corrosion-resistant, and eco-friendly, they are lightweight, facilitate easy construction, and cost only two-thirds of traditional materials. Their ecological pore design promotes plant growth and provides habitats for fish and shrimp, delivering outstanding bank protection with a service life of up to 50 years. In urban infrastructure projects, plastic-steel sheet piles are widely used in deep foundation pit support, tunnel shoring, retaining walls, breakwaters, and wharf walls, playing a vital role.
