Compared to Z - Pile, PS sheet piles offer minimal beam strength. They are typically used for circular cell design. This application applies hoop stress to the sheets, which is transferred to the interlock. The PS Thumb & Finger (T&F) interlock is a three-point contact connection that provides superior pull strength to counter those forces.
Although circular cell design with flat sheets is considered old technology, it is a solid, proven application that is still used by today's engineers. The OPEN CELL® design is an innovative concept that has taken this "old technology" into the 21st century. The OPEN CELL® trademark is used with the permission of PND Engineers, Inc.
Steel sheet piling is a manufactured construction product with a mechanical connection "interlock" at both ends of the section. These mechanical connections interlock with one another to form a continuous wall of sheet piling. Steel sheet pile applications are typically designed to create a rigid barrier for earth and water, while resisting the lateral pressures of those bending forces. The shape or geometry of a section lends to the structural strength. In addition, the soil in which the section is driven has numerous mechanical properties that can affect the performance.
Steel sheet piling is classified in two construction applications, permanent and temporary. A permanent application is "stay-in-place" where the sheet piling wall is driven and remains in the ground. A temporary application provides access and safety for construction in a confined area. Once the work is completed, the sheet piling is removed.
