Japan sheet pile is also called Larssen sheet piling. There are several hot rolled mills in Japan.For examples, SP,JFE, JFESP, FSP ( Nippon / Fuji ), GSP ( Corus ), ISP ( INISTEEL ), JSP ( Arbed ), KSP (Kawasaki), NKSP (NKBS), SKSP (Sumitomo), NS-SP,TSP (Tokyo Steel).It is the most widely used bulkhead material and can be driven into the foundation without extensive excavation. The original seabed is a layer of medium dense to very dense silty sand, overlying a medium dense to very dense silty gravel layer with sandstone bands up to 8.0m thick. It can be driven into hard, dense soils and even soft rock. A comprehensive range of sections in both Z and U forms with a wide range of sizes and weights is obtainable in various different grades of steel which enables the most economic choice to be made to suit the nature and requirements of any given contract. Japan sheet piles are suitable for structures requiring deep penetration, large water depth, free standing or the combinations.
