Z-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 and can be used in a wide variety of applications.

Applications of Z-shaped Sheet Piles

• Retaining walls
• Cofferdams
• Parking garages
• Environmental barrier walls
• Steel bulkhead walls

Types of Z-piles

NZ Sheet Pile

Nucor’s NZ sheet piles are offered exclusively by Nucor Skyline. The NZ sections offer the largest range and best strength to weight ratio of domestically produced sheet piling. The sections are also the widest of domestically produced sheets, which reduces the number of piles that have to be driven. The Larssen interlock is exceptionally water tight and all of the NZ sections interlock with one another.

PZ Sheet Pile

PZ sections have been manufactured in the US for many years and are widely recognized by the ball and socket interlock. The PZ sections are good sections for reuse because of their compactness and the durability of the interlock. The ball and socket interlock also allows as much as ten degrees of swing for turning tight curves on the jobsite.

SCZ/SKZ Sheet Pile

SCZ/SKZ piles are cold formed sheet piles produced from steel coil. SCZ/SKZ shapes are generally wide, efficient and allow for greater swing angle than hot rolled sheets. There are many options to choose from that are readily available due to tight and flexible rolling schedules. The variety of SCZ/SKZ sections is made up of five different sizes in several thicknesses.
