About us

ArcelorMittal, as a global leading steel producer, committed in 2021 to reduce its CO₂-eq. emissions in Europe by 35% by 2030 and aims at reaching carbon neutrality globally by 2050. Our values are Safety, Sustainability, Quality and Leadership.

ArcelorMittal Sheet Piling is the worldwide leader in sustainable steel sheet piling technology, providing the most innovative foundation solutions. Our products are used worldwide for the construction of quay walls, waterways, flood protection barriers, mobility infrastructure projects and containment structures. ArcelorMittal Sheet Piling oversees the sales, marketing and promotion of foundation solutions. Our steel sheet piles are manufactured in Europe.

We offer complete package solutions, based on our wide range of products and services, expert technical support from the early design stages of a project to its completion, customized fabrication, just-in-time delivery and after-sales services. Our innovative solutions and technical support allow the design of optimized, sustainable and efficient steel sheet piling solutions.

ArcelorMittal’s piling series are especially suitable for quickly and reliably building cost-effective structures. They are characterised by excellent section properties, for instance a highly competitive ratio of section modulus to weight, as well as high moments of inertia. Steel sheet piles and foundation products are manufactured according to the European standards, but they can also be supplied according to other international standards (e.g. ASTM). 

Decarbonisation is the most important aspect of ArcelorMittal’s long-term strategy. For several years already, the EcoSheetPile™ range has been produced from 100% recycled, recyclable and reusable steel. It is a major contributor to the circular economy. Launched in 2021, the EcoSheetPile™ Plus brand, essential part of ArcelorMittal’s XCarb™ recycled and renewably produced initiative to reach carbon neutrality by 2050, is made from recycled material with additionally 100% renewable electricity.

As project owners start integrating green credentials assessment rules in their tendering processes with fair monetization processes, bids that offer sustainable construction solutions with a reduced carbon footprint have a tangible advantage.

Production Centres

Steel sheet piles and combined walls supplied by ArcelorMittal Sheet Piling are produced in 5 different facilities in Europe:

Cold formed steel sheet piles

Production facilities in Luxembourg

ArcelorMittal Luxembourg is one of the European top producers of long products such as beams, steel sheet piles and other special sections, which lead the path to the modern construction industry providing innovative steel solutions.

These construction products are produced in two steel plants located in Belval and Differdange. Both facilities produce 100% recycled steel using scrap as its main raw material. The scrap is melted in an Electric Arc Furnace (EAF), cast and shaped into beam-blanks in the steel mill, then stored before being reheated in the rolling mill's furnace, and finally hot rolled to its final shape.

ArcelorMittal Belval & Differdange is certified ISO 9001, ISO 14001, ISO 45001, ISO 50001 and BES 6001.

ArcelorMittal also produces rails, special sections and steel wire products in other facilities in Luxembourg.

Belval mill

The steel plant located in Belval is the world’s largest rolling mill of hot rolled steel sheet piles and has been playing a leading role in the development of piling technology for over 100 years (formerly ARBED).

The Belval site consists of a steel shop with an electric arc furnace and a continuous caster. It has two specialised rolling mills, one dedicated exclusively to steel sheet piles (Mill 2), and one dedicated to standard steel sections (TMB).

The first steel sheet piles that were rolled in 1911 and 1912 were the Ransome and Terre Rouge profiles. Since then, the available range produced in ArcelorMittal’s Mill 2 has undergone a continuous improvement process that allows the production of the revolutionary AZ® sections (Z-type) up to 800 mm (31.5") wide, as well as the current U-type sections with section widths up to 750 mm (29.53").

Note that Mill 2 in Belval is the only rolling mill in the world that has the knowledge and state-of-the-art technique to produce steel sheet piles in the more corrosion resistant AMLoCor® steel grade.

The series of hot rolled steel sheet piles manufactured in Belval are

• Z-type: AZ-800 | AZ-750 | AZ-700 | AZ
• U-type: AU | PU
• straight web type: AS 500

Differdange mill

The Differdange mill is composed of a steel shop with one electric arc furnace and a continuous caster, as well as one rolling mill, known as the Grey Rolling Mill. Differdange produces the HZ-M sheet piles, as well as heavy sections - including the Jumbo sections used in skyscrapers.

The Differdange mill holds several world records, including that for the first beam measuring one meter high (3.28 ft high), the beam with the heaviest metric weight (1 370 kg/m) and the largest beam (1 100 x 400 mm).

The HZ-M® sections are the stiffest sheet piles in the world, the key element to build up the most competitive high section modulus combined wall systems. Their main applications are harbour construction and deep excavations all over the world.

Beams produced in the Grey Rolling Mill have been used for the most prestigious landmarks, including the Freedom Tower in New York (USA) and the World Financial Centre in Shanghai (China).

The series of hot rolled steel sheet piles manufactured in Differdange is

• HZ-type: HZ-M
