Define Sheet piles

Sheet piles are used in many types of temporary works and permanent structures. The sections are designed to provide the maximum strength and durability at the lowest possible weight consistent with good driving qualities. The design of the section interlocks facilitates pitching and driving and results in a continuous wall with a series of closely fitting joints.

A comprehensive range of sections in both Z and U forms with a wide range of sizes and weights is obtainable in various different grades of steel which enables the most economic choice to be made to suit the nature and requirements of any given contract.

The advantages of U-shaped sheet piles are multiple:

* wide range of sections forming several series with various geometrical characteristics, enabling the choice of technically and economically optimised sections for each specific project

* combination of great wave depth and high flange thickness leading to excellent statical properties

* symmetrical form of single elements resulting in great aptitude for re-use

* possibility of assembling and fixing sheet piles into pairs at the mill providing better installation quality and performance

Among the essential characteristics of Z-shaped sheet piles are the continuous form of the web and the specific location of the interlock symmetrically on both sides of the neutral axis. These two attributes have a positive influence on the section modulus. The AZ series combines a section with extraordinary characteristics with the quality-proven Larssen interlock. Z-shaped sheet piles present the following advantages:

* extremely competitive section modulus/mass relation

* increased inertia and thus reduced deflection allowing the choice of high yield strength steel grades for the most economical solution

* large width resulting in high installation performance
