Steelsheet piles are long structural sections with a vertical interlocking systemthat creates a continuous wall. The walls are most often used to retain eithersoil or water. The ability of a sheet pile section to perform is dependent uponits geometry and the soils it is driven into. The pile transfers pressure fromthe high side of the wall to the soil in front of the wall.
There are permanent and temporary applications. Permanentsheet piles remain in the ground and serve as permanent retaining structures.Temporary sheet piles are designed to provide safe access for construction, andare then removed.
Z-shaped sheet piles are called Zs because the single piles areshaped roughly like a horizontally stretched Z. The interlocks are located asfar away from the neutral axis as possible to ensure good shear transmissionand increase the strength-to-weight ratio. Z piles are the most common type ofsheet pile in North America and can be used in a wide variety of applications.Retaining walls, cofferdams, parking garages, environmental barrier walls, andbulkhead walls for ports are just a few of their varied uses.
