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.
Ports
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.

New sections, catalogue, and software for the HZ®-M Steel wall system
The HZ®-M Steel wall system, which is an HZ/AZ combined wall system, is one of the most preferred solutions for port structures and other deep excavations. A new section (HZ 630M), a 2020 catalogue, and updated software are now available.
New HZ 630M section of the HZ®-M steel wall system
The new HZ 630M section completes the existing range of the already large HZ®-M series. It was developed mainly for use in very hard driving conditions (installation in compact soils) and for structures with restrictions on the height of the system.
The flange thickness is 24.2 mm and the maximum height of an HZ 630M solution is only 672 mm (including connectors).
This new profile is available from now on and replaces the HZ 680M LT.
2020 HZ®-M Steel wall system catalogue available
The new catalogue has been extended to systems based on the latest HZ®-M king pile range combined with our enhanced AZ®-800 steel sheet pile generation as intermediaries. It provides new technical data needed for design according to Eurocode and includes a revised table for resistance to water pressure.
HZM™-AZ® Stresses software
An updated version of the HZM™-AZ® Stresses software is available.
Stress analysis for the HZM™ / AZ® combined wall system is based on the 'allowable stress design' method. It allows the user to easily select a solution based on bending moments and chosen safety factors on the steel stresses. The user can also prepare a basic material list for a straight retaining wall.
Additional features of the 2019 update include: calculating the wall properties of any combination with an AZ® infill sheet pile ranging from AZ® 12-770 to AZ® 28-700N and the new HZ 630M piles.

The many applications of ArcelorMittal crane rails
From port and terminal projects to giant cranes or retractable roofs (the latest trend in sport stadiums), ArcelorMittal crane rails are used in many applications and are present in every continent.
Working closely with customers
ArcelorMittal Europe – Long Products Rails & Special Sections is working closely with its customers to develop specific rails and new products according to their needs. Flexibility is another key factor in improving customer service. We can supply standard rail lengths from 6 to 36 metres, but other lengths are available upon request as well as finishing possibilities (cuts, special cuts, drilling, machining, bending, blasting-painting, etc.).
Incomparable knowledge, selection, and expertise
Crane rails are produced in several steel grade qualities and specifications according to customers’ requirements. Historical crane rails producer, ArcelorMittal Europe – Long Products Rails & Special Sections has built an incomparable knowledge and expertise of this product range. The company has also created with its customers numbers of rails as per all the MRS range used worldwide in major port projects and has established levels of quality control even stronger than the basic standards to secure our customers in their choice of a key product related to most often critical applications.
ArcelorMittal Europe – Long Products Rails & Special Sections has the largest products and grades portfolio, from the full range of DIN crane rails, MRS crane rails, CR crane rails, and many other specific rails, with hundreds of references in main ports worldwide.
Retractable roofs: a new trend in stadium construction
Retractable roofs are getting more and more popular in stadium construction, and ArcelorMittal crane rails are already present in some spectacular stadiums all around the world. Retractable roofs are designed to move panels that weigh hundreds of pounds in just minutes and they allow to control the stadium’s interior environment more effectively as they can be closed during inclement weather and opened on sunny days. After the roofs, retractable pitches might soon become the new trend.
From the world’s largest crane to the latest Ariane rocket
Another impressive application of crane rails is giant cranes. ArcelorMittal Europe – Long Products Rails & Special Sections has supplied crane rails for Sarens’ SGC-250, the largest crane in the world, capable of lifting 5000 tonnes, which is equal to 1408 elephants, 63 trains, or 20 planes.
Another major application is the launching pad of the Ariane 6 rocket, for which crane rails have been supplied for the construction of the rail track.

ArcelorMittal sheet piles for antarctic research vessel wharf
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.
The British Antarctic Survey
The British Antarctic Survey has a rich history of conducting scientific research at the earth’s southern pole. Since their first ship arrived in 1947, specialised vessels have allowed BAS to access remote areas that would not be possible otherwise.
The commissioning of the RRS Sir David Attenborough is part of the United Kingdom’s polar infrastructure investment programme. It is designed to keep Britain at the forefront of world-leading research in one of the most inhospitable regions on earth.
Research at the ends of the earth
Launched in 2018, the RRS Sir David Attenborough will commence sea trials in autumn 2019. The vessel will enable scientists to research oceans, ice, and the atmosphere. This floating, multidisciplinary research platform will give them access to state-of-the-art facilities including a scientific moon pool and containerised laboratories.
At almost 129 metres, the new vessel is much longer than its predecessors. This has necessitated the building of a new wharf at Rothera Research Station. BAM Nuttall, a leading construction and civil engineering company, is demolishing the existing wharf and constructing its larger replacement.
ArcelorMittal and BAM Nuttall worked closely on the design of the new wharf. The quay wall is made up of 200 sheet piles which are connected to a steel structure. Every pile has several holes for connections which are placed in different locations across the sheets, making each one unique. Fundamental to this close partnership is ArcelorMittal Sheet Piling’s ability to offer a complete solution comprising engineering design support, further fabrication and customisation, and bespoke logistics.
The AZ® piles selected for the quay wall have excellent strength-to-weight ratio. Weight was an issue as the sheet piles had to be shipped more than 11 000 kilometres to the site. Handling on site was also a consideration. AZ® piles are made from 100% recycled steel, helping to keep the total carbon footprint of the project down.
Prefabrication before shipping
ArcelorMittal and BAM Nuttall decided to pre-fabricate the sheet piles in the UK due to adverse weather conditions in the Antarctic. This meant that work normally done on site, such as welding and fitting of brackets, had to be carried out before the sheet piles were shipped.
The sheet piles arrived at Rothera in January 2019 after a month at sea. Demolition of the existing wharf also began in January and the first frames for the new wharf were installed in March. As work can only take place during the polar summer, the wharf is not expected to be fully operational until mid 2020.
When it is complete, the new wharf will allow polar research ships such as the RRS Sir David Attenborough to continue scientific investigation into deep-sea biology, seafloor geology, and climate change. Working in co-ordination with autonomous underwater vehicles (AUVs) and other equipment, the ship will enable scientists to capture, analyse, and share data that will give us a better understanding of our planet. It will also provide essential evidence to help policymakers determine what action we must take to protect the earth.
