Sheet pile, a versatile construction material, is typically made of steel with high strength and corrosion resistance. It comes in various shapes like U-type, Z-type and straight web type. Widely used in foundation engineering, it excels in temporary or permanent retaining structures, such as cofferdams for bridge construction, flood barriers and deep excavation support. Its interlocking design forms a tight wall, effectively preventing soil erosion and water seepage. Easy to install and remove, it offers cost-effective solutions while ensuring construction safety and stability.
