- SLHZ king piles as structureal supports,
    - SLZ sheet piles as intermediary elements,
    The HZ king piles fulfil two different structural functions:
    - retaining menbers for soil and hydrostatic pressures
    - bearing piles for vertical loads

     All combinations are based on the same principle: structural supports comprising 1 or 2 SLH king pile sections alternating with intermediary double SLZ sheet pile sections. The intermediary sheet piles have a soil-retaining and load-transferring function and may be shorter than the SLH primary piles. Depending on the structural combination and steel grade adpoted, bending moments up to 9000kNm/m can be safely resisted.
