Some introduction of steel sheet piling

Steel sheet piling is a hot-rolled structural shape with interlocks on the flange tips. The interlocks permit individual sections to be connected to form a continuous steel wall which is earth-tight and water resistant. Because it is readily available and transportable, steel sheet piling is in many cases a fast and economical solution to an owner’s need for a durable, long lasting wall system.

Applications are far-reaching, and include, for permanent construction, retaining walls, bulkheads, bridge abutments, graving docks, cut-off walls, mooring dolphins and pier protection cells. Common uses also include temporary structures, such as trenches, cofferdams for building excavations, bridge piers, and lock and dams on the inland river system. At the end of the project, the steel sheet piles can be extracted, and the steel reused.

Hot rolled steel sheet piling is an engineered product meeting one of several applicable ASTM specifications. These specifications, combined with the steel sheet piling producer’s quality control programme, provide a quality product which is ductile, durable and long-lived. In fact, construction in West London, UK, recently unearthed steel sheet piles over 80 years old.

When pulled from the native wet soil, the piles were so well preserved, the original mill marks could be seen. Steel pilings in continuously submerged conditions tend to have relatively low corrosion rates, because oxygen levels decrease with depth. Steel pilings are also a zero-waste product: after extraction, they can be reused or 100% recycled.
