Benifits of steel sheet pile

Steel sheet pile easily adapt to variable site conditions to achieve uniform minimum capacity with high reliability, thus eliminating uncertainty due to site variability. Steel sheet pile are usually installed to established criteria (e.g., minimum blow count per unit penetration, sometimes with a minimum penetration). Because they are normally driven to a blow count to assure the desired minimum capacity, pile lengths may vary when subsurface conditions are not uniform. Steel sheet pile may either be cut-off to shorten their length or spliced to extend their length. Splice designs usually meet or exceed the strength of the pile itself. Pile shoes (or "points") can be added to assist penetration requirements and provide very reliable contact with rock. The optimum length is used for each pile which accommodates all site conditions.

Steel sheet pile adapt well to unique site conditions and restrictions. They are ideally suited for marine and other near shore applications. There are no special casings required and there are no delays related to the curing of concrete. Piles driven through water can be used immediately, allowing construction to proceed in a timely manner. For bridges or piers, steel sheet pile can be quickly incorporated into a bent structure allowing the bridge or pier itself to be used as the work platform for succeeding piles in top-down construction.

To minimize disturbance in wetlands or allow work over water, steel sheet pile can be used to construct temporary trestles. Piles installed to meet any temporary construction need can be extracted when the need is ended.

In earthquake prone regions, large diameter steel sheet pile are well suited to resist seismic forces. Non-displacement pile sections (e.g. H piles) can be utilized to minimize vibration effects on nearby existing structures. In corrosive environments, coatings and/or additives can be used to mitigate the effects of corrosion thereby lengthening the service life of a structure. Coatings can also be used to mitigate the effects of negative skin friction.
