Steel sheet piles
Steel sheet piles offer a timely and cost-effective solution for many of the problems modern ports are currently facing. A sheet pile wall placed in front of an existing quay wall allows the harbour bed to be dredged to depths required by modern vessels.
Sheet piles have also proven their efficiency when it comes to the construction of new ports. The straightforward installation and reduced workforce requirement allows the new port to be operational in a short period of time.
Through constant innovation, today’s U and Z shaped piles form some of the most advanced solutions for constructing and deepening harbour walls.
To offer the best products on the market which meet the requirements of the dynamic shipping industry, ArcelorMittal’s research team is continuously developing and redefining their sheet pile range. The latest development includes the addition of the GU 11 N range to the U section family in 2017.
With more than 100 years of experience in the development and production of steel sheet piles, ArcelorMittal offers the most extensive product range and the highest level of expertise in the field of foundation solutions and harbour structures.

Economical and safe design approaches for steel sheet piling structures in highly seismic zones
Widely used for the construction of a variety of structures such as quay walls and breakwaters in harbours, bank reinforcements on rivers and canals, underpasses, as well as global hazard protection schemes, sheet piles have proven their performance in seismic areas in many countries around the globe.Chile, the country that has suffered the strongest earthquakes in recorded history, provides an excellent example: Whereas its concrete-based ports have been severely damaged, the Port of Mejillones, constructed in 2003 using an HZ®/AZ® combined wall for the quay wall and AS 500 straight web sheet piles for the breakwater, has not suffered any damage throughout many heavy earthquakes with magnitudes of up to 7.7. This is the perfect example of the effectiveness of flexible sheet pile structures under extreme seismic conditions.Nevertheless, a certain reluctance to use sheet piles in seismic areas remains common among some designers. This concern may come from their experience of conventional design methods which do not favour flexible walls in seismic areas. These design methods are usually comprised of pseudo-static calculations using the Mononobe-Okabe theory (1931).Numerical studies and physical experiments (centrifuge testing) have shown that these conventional methods of design are overestimating the loads on retaining walls - especially in the case of flexible walls. Although EN 1998-5 allows for a reduction of the seismic action depending on the acceptable displacements (reduction factor “r”), this only applies to gravity walls and not to anchored walls such as sheet pile walls, despite their inherent ductility.Today, powerful design tools using Finite Element Modelling (FEM) allow for dynamic calculations that can accurately predict the behaviour of the retaining walls undergoing different seismic loadings, including internal forces, deformations, increases in pore water pressures, and expected modes of failure.Article

ArcelorMittal sheet piles for antarctic research vessel wharf12 September 2019
Construction has begun on a new wharf at the British Antarctic Survey (BAS) Rothera Research Station, and Z sections from ArcelorMittal Europe – Long Products Sheet Piling are playing a leading role. The new wharf will be used to berth the RRS Sir David Attenborough. Commissioned by NERC and built by Cammel Laird for operation by BAS, this is one of the most advanced polar research vessels in the world. Construction of the wharf is being carried out on site and will take two years to complete.Project News
