HEAVY-DUTY "Z" SHEET PILING - PZ

PZ sheet piles feature mechanical "ball and socket" connections that allow each steel sheet to interlock with another and create a rigid barrier for earth and water while resisting the lateral pressures of these forces. The ball and socket interlock also permits flexibility in setting while remaining very durable under driving conditions compared to other systems.

HIGH EFFICIENCY Z SHEET PILE - PZC

Shandong Linghang Steel Group Co., Ltd.PZC sheet piling sections utilize a design that is wider, lighter and stronger than traditional Z-profile sheet piling.  Given these characteristics, PZC sheet piling yields both lower material costs and fewer piles that need to be installed making it significantly more cost-effective.

The PZC design still features the popular ball-and-socket interlock while providing greater degrees of swing and flexibility than alternative Z-profile sheet piling sections.  This makes it easier to set, drive, and establish precise wall layouts.  PZC sheet piling is commonly used in marine, foundation, transportation and environmental applications.

ESZ STEEL SHEET PILES

Grade 60 steel sheet piles.  These sheet piles give a quantifiable improvement of 20% in design life compared to a sheet pile in grade 50 steel. On a project with a life expectancy of 75 years that’s an additional 15 years of life.

Using grade 60 in design can often lead to reducing a sheet pile size to carry the same loading. Weight saving of 30% or more are realistic.

FLAT SHEET PILING

Typically used for circular cell design applications, flat sheet pile is a proven technology that is still used on many projects. While these steel sheet piles offer much less beam strength than Z piles, the sections use a Thumb and Finger interlock with a three-point contact connection to generate significant pull strength to counter the hoop stress applied to them.

Everything You Need to Know About Steel Sheet Piling

INTRODUCTION

A steel sheet pile is one of the most common construction materials generally used for earth-retaining walls. These earth-retaining structures may be permanent or temporary in nature, depending on the need of the project. 

Projects such as ports and bridges may require the steel sheet piles to be installed permanently to prevent the backfill soil from collapsing during the structure’s design life. 

On the other hand, building construction projects involving basements and/or deep excavations will require temporary excavation supports as the concrete basement walls are constructed. 

WHAT ARE STEEL SHEET PILES USED FOR?

Steel sheet piles are slender structural members of varying lengths and cross sections, that are connected using interlocks at each end of the panel to make a continuous wall. Sheet piles are usually installed as part of an earth-retaining structure for slope protection, and excavation protection. 

Marine structures such as jetties and quay walls use sheet pile walls to retain the backfill soil used for raising the finished floor level of the docking areas. Sheet piles also help in the mitigation of rapid groundwater seepage for these types of projects.

For most engineering projects, steel sheet piles are usually installed for falsework or temporary excavation protection applications. These include basement and tunnel construction. 

STEEL SHEET PILE BENEFITS

The main advantage of steel sheet piles is its applicability for a wide variety of engineering projects.

In addition to that, steel sheet piles would potentially require less installation time as compared to reinforced concrete for retaining wall applications, where curing of the concrete would take several days prior to the next pouring activities. 

Sheet piles are also generally lighter than reinforced concrete and can be transported more easily. 

In addition, issues pertaining to deterioration of material quality during transport is kept to a minimum, unlike concrete, where there may be material quality issues occurring while it is being brought to the project site.

In terms of sustainability, steel sheet piles can be recovered from temporary excavation protection structures and can be utilized again for future construction projects. For permanent structures, steel sheet pile ways are also found to perform well when subjected to various loads. This is due to the high bending stresses it can withstand.
