There are three forms or shapes of steel sheet piles: Z-shaped, U-shaped and Straight Web Sections.Z-shaped sheet piles are considered to be the most efficient of the shapes. They are used for intermediate and deep wall construction and commonly for tied back and cantilever retaining walls. U-shaped profiles are used for similar applications, but their resistance to bending is lower than Z-shaped piles.
We sell and rent three different hot-rolled, "Z" type sheet piling products, flat piling and combination systems to ensure that we can match the needs of your application.The Z shape of each section lends to its structural strength which is determined not only by the size, but also by the thickness of the steel. Of course, the soil conditions in which the section is driven will also affect the performance of the foundation or wall.
Hot Rolled Sheet Piles are formed by profiling the steel with high temperatures as the rolling process occurs. Typically, hot rolled sheet piles are produced to BS EN 10248 Part 1 & 2. Greater thicknesses are achievable than cold rolled sheet piles. The interlocking clutch tends to be tighter as well.
Like other steel piling shapes, sheet piling is driven into the ground to provide stability and support for a range of construction applications. As its name suggests, these are steel sheets that form a support wall, rather than the round or H-shaped cross sections of other piling shapes. Sheet piling has both temporary and permanent uses, usually as retaining walls for excavation, underground structures, or seawalls.
U-type Steel Sheet Pile U-type profile interlocked on both sides to form a continuous wall with centerline in the middle of a double U section wall.
Z-shaped steel sheet piles are produced in a zigzag form and are typically driven in crimped or welded doubles. These piles offer a unique set of benefits, particularly for port construction and deep foundations where their higher modulus and use as intermediate piles in tubular & HZ combination walls is advantageous. Advantages of Z-Shaped Steel Sheet Piles Flexible Design and High Section Modulus: Z-shaped steel sheet piles offer a high section modulus and mass ratio, allowing for flexible design according to the project's needs. Higher Moment of Inertia: The higher moment of inertia increases the stiffness of the sheet pile wall and reduces displacement deformation. Large Width: The large width of these piles saves time during lifting and piling. Corrosion Resistance: Parts of the sheet pile that are prone to serious corrosion undergo thickening treatment, enhancing corrosion resistance. Lighter Weight: The weight per square meter of a Z sheet pile is always less than that of a U sheet pile for a similar section modulus, making it a more efficient choice. Use as Infill Pile: Z-shaped sheet piles can be used as infill piles together with steel pipes and H-beams. They are typically used to achieve a very high modulus.
