Japanese sheet pile is also called Larsen sheet pile. There are several hot rolling mills in Japan. For example, SP, JFE, JFESP, FSP (Japan/Fuji), GSP (Corus), ISP (INISTEEL), JSP (Arbed), KSP (Kawasaki), NKSP (NKBS), SKSP (Sumitomo), NS-SP, TSP (Tokyo Railway). It is the most widely used bulkhead material and can enter the foundation without a lot of excavation. The original seabed is a layer of silt with medium density to very dense, covering medium density to very dense silty gravel layer sheet pile manufacturers. The thickness of sandstone zone is up to 8.0 meters. It can be driven into hard, dense soil or even soft rock. Various models, sizes and weights in the form of Z and U can be obtained in various grades of steel, which enables the most economical choice to be made to meet the nature and requirements of any given contract. Japanese sheet piles are suitable for structures requiring deep penetration, large water depth, free standing or combination.
