Steel Sheet Piling

Steel sheet piles are long structural sections with a vertical interlocking system that create a continuous wall. The walls are often used to retain either soil or water. The ability of a sheet pile section to perform is dependent upon its geometry and the soils it is driven into. The pile transfers pressure from the high side of the wall to the soil in front of the wall.

Nucor Skyline supplies a wide variety of sheet pile from leading manufacturers. In piling, hot rolled steel sheet pile and cold formed steel sheet pile are two primary methods of manufacturing sheet pile. While there are differences between these two methods, the most important distinction is the interlock. Since hot rolled steel sheet piles are produced from steel at high temperatures, the interlock tends to be tighter than its cold formed steel sheet pile counterpart. Normally, looser interlocks are not recommended in extremely hard driving conditions or for walls requiring low permeability. Otherwise, the two types of sections perform similarly.

Applications of Sheet Pile

Around the world, Z-pile, named for its shape, is used for various applications, both permanent and temporary. Temporary sheet piles provide safe access for construction and are then removed; however, they are sometimes left in place. Cofferdams and support of excavation are two of the most common forms of temporary uses of sheet piling. Permanent sheet piles remain in the ground and serve as permanent retaining structures such as, levee strengthening, retaining walls, breakwaters, bulkheads, and environmental barrier walls. In addition to these traditional applications of sheet piling, steel sheet piles are also used to take combined vertical and lateral loading for bridge abutments and underground parking garage projects.

Bending strength and stiffness are the primary design considerations of sheet piling. Durability of the section, especially in permanent salt water applications, must also be taken into account in sheet piling. Drivability of the sheet piles is often overlooked and can control the selection of the sheet piles.

Flat sheet piles (straight web sheets) are used in the construction of cellular structures. Cellular cofferdams are utilized to dewater large areas during the construction of locks and dams and are also employed as permanent walls when loads are exceptionally high or there is little or no soil for embedment. Large embedment is generally not necessary, since the cells are gravity structures and the tension is resisted by the interlock. Unlike Z-pile or combination walls, interlock strength is the main design consideration for cellular cofferdams. The weight of the cell and the resistance of the flat sheet interlocks form the stability of the structure.

Z-type Sheet Piles

Z-type Sheet Piles

Z-shaped sheet piles are called Z’s, because the single piles are shaped roughly like a horizontally stretched Z  Learn More

Flat Web Sheet Piles

Flat Web Sheet Piles

Flat sheet piles work differently from other sheet piles. Most sheet piles rely on their bending strength and stiffness to retain the soil or water  Learn More

U-type Sheet Piles

U-type Sheet Piles

U sheet piles retain soil and water just like Z piles with one important difference: U piles have the interlock on the neutral axis  Learn More

Pan type Sheet Piles

Pan type Sheet Piles

The pan shaped cold form sheet piles are much smaller than most other sheet piles and are only intended for short, lightly loaded walls  Learn More
