Steel sheet piling is 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.
For applications where corrosion is an issue, sections with
minimum thickness can be delivered to maximise the effective life of the
structure. The usual requirements for minimum overall thickness of 10 mm, 12 mm
or 1/2 inch can be met. Corner and junction piles are available to suit all
requirements.
Typical Uses
River control structures and flood defence
Steel sheet piling has traditionally been used for the
support and protection of river banks, lock and sluice construction, and flood protection.
Ease of use, length of life and the ability to be driven through water make
piles the obvious choice.
Ports and harbours
Steel sheet piling is a tried and tested material to
construct quay walls speedily and economically. Steel sheet piles can be
designed to cater for heavy vertical loads and large bending moments.
Pumping stations
Historically used as temporary support for the construction
of pumping stations, sheet piling can be easily designed as the permanent
structure with substantial savings in time and cost. Although pumping stations
tend to be rectangular, circular construction should be considered as
advantages can be gained from the resulting open structure.
Bridge abutments
Abutments formed from sheet piles are most cost effective in
situations when a piled foundation is required to support the bridge or where
speed of construction is critical. Sheet piling can act as both foundation and
abutment and can be driven in a single operation, requiring a minimum of space
and time for construction.
Road widening retaining walls
Key requirements in road
widening include minimised land take and speed of construction particularly in lane rental situations. Steel
sheet piling provides these and eliminates the need for soil excavation and
disposal.
