U sheet pile has many advantages as following:

    1.It combines great profile depth and has excellent statical properties;

    2.It is quite suitable for re-use due to the symmetrical form of the single element;

    3.It is possible to assemble the piles into pairs in the factory, this way could improve the quality and performance of installation;

    4.Good corrosion resistance performance 

     Z sheet pile, with continuous form of the web and the location of the interlock symmetrically on each side of the eneutral axis, it has great improvement on the section modulus. Followings are the main advantages:

     1. Large width, good installation performance;

     2. Extremely competative of section - modulus to mass ratio;

     3.increased inertia for reduced deflection

     4.Good corrosion resistance

    The SLH/SLZ wall is a combined system incorporating:
