Z Shape Steel Piles Sheet HR CR For Cofferdam Construction

Z Hot Rolled Steel Sheet Pile

Sheet piles are structural members which when interlocked to another, will form a continuous wall, generally for retaining earth or water. Sheet piling has historically been made of steel, concrete, wood, aluminum or other materials. Steel is by far the dominant choice, due to ready availability, relative strength, and ease of handling, storage and installation.

Sheet pile shapes have evolved over the years from simple channel sections with crude fabricated locks, to “U” shapes with integral, rolled-on interlocks, to today’s wide range of high strength "Z" shapes.

The Z type configuration is generally considered the strongest and most efficient.

These shapes resemble wide-flange beams, having a web and two flanges. The interlocks are located out on the flanges at maximum distance from the neutral axis, and this provides a high section modulus for resisting bending moments.

Because of this, Z-shapes have traditionally been used for heavier construction projects. However, they are now complemented by the arch or U shapes for lighter work, and lightweight Z-shapes have been also introduced into the marketplace.

Because of their inherent strength, Z-piles can be handled and shipped with less exposure to possible damage than some other style sheets.

Z-piles are generally used in constructing straight wall structures – cofferdams, bulkheads and retaining walls.

Z Hot Rolled Steel Sheet Pile Advantages:

– Extremely competitive section-modulus-to-mass ratio.
– Increased inertia for reduced deflection.
– Large width, resulting in good installation performance.
– Good corrosion resistance, the steel being thickest at the critical corrosion points.

The essential characteristics of HRZ Hot Rolled steel sheet pile are the continuous form of the web and the location of the interlock symmetrically on each side of the neutral axis. Both aspects have a positive influence on the section modulus.
