Steel Sheet Piling

Steel Sheet Piles

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 steel sheet piling. In piling, hot rolled steel sheet pile and cold-formed steel sheet pile are two primary methods of manufacturing sheet piles. While there are differences between these two methods, the most important distinction is the interlock. Since hot-rolled steel sheet piling is 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 Steel Sheet Piles

Levee Strengthening
Retaining Walls
Breakwaters
Bulkheads
Environmental Barrier Walls
Bridge Abutments
Underground Parking Garages

Types of Steel Sheet Piles

Z-type Sheet Piles

Z-shaped sheet piles are called Zs because the single piles are shaped roughly like a horizontally stretched Z. The interlocks are located as far away from the neutral axis as possible to ensure good shear transmission and increase the strength-to-weight ratio. Z piles are the most common type of sheet pile in North America.

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. Flat sheet piles are formed in circles and arcs to create gravity cells. The cells are held together through the tensile strength of the interlock. The tensile strength of the lock and the allowable rotation of the lock are the two main design characteristics. The flat sheet pile cells can be made to huge diameters and heights and withstand a great deal of pressure.
