ArcelorMittal Luxembourg is a top producer of long products like beams and steel sheet piles that provide innovative solutions to the modern construction industry. Heavy Jumbo sections and high performance steel grades from ArcelorMittal in Differdange have a worldwide reputation for use in high rise buildings and save up to 40% of material weight (and accordingly CO2). Steel sheet piles from ArcelorMittal in Belval have achieved leadership in this market segment through high quality and reliability.
Belval | Luxembourg (hot rolled sheet piles)
ArcelorMittal Belval (formerly known as ProfilArbed) 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. The first steel sheet piles were rolled in 1911 and 1912: the ‘Ransome’ and ‘Terre Rouge’ piles. Since then the production program of ArcelorMittal’s mill in Belval has undergone constant improvement and development to include U- with widths of up to 750 mm (AU) and Z-piles up to 800 mm wide.
ArcelorMittal’s piling series are especially suitable for building reliable structures rapidly and cost-effectively. They are characterized by excellent section modulus to weight ratios and high moments of inertia. Steel sheet piles are used worldwide for the construction of quays walls and breakwaters in harbors, locks, and for bank reinforcement on rivers and canals. Other applications are temporary cofferdams in land and in water, permanent bridge abutments, retaining walls for underpasses or underground car parks, impervious containment walls, etc.
Dabrowa | Poland (hot rolled sheet piles)
In Dabrowa-Gornicza, part of ArcelorMittal Poland, the rolling of steel sheet piles started in 1979. The first section was named “G1”, and the production capacity was 7,000 t per year. Later, in 1984, the production was boosted to 40,000 t a year, and the initial section was renamed “G62”. The mill continued enlarging its product portfolio, and after the creation of ArcelorMittal in 2006, more cost-effective sections were developed in the Polish mill.
Even though the range was continuously extended and optimized by using the most modern rolling technology that allows for manufacturing more efficient sheet piles, the “original” sheet pile is still part of the current rolling program (GU 16-400).
Steel sheet piles have become a key product in the portfolio of Dabrowa’s “Heavy Mill”, which is focusing on adding value to the products for the benefit of our customers. Currently, six ranges of sheet pile sections and steel grades up to S460 AP are produced, leading to more efficient piles.
Messempré | France (cold formed sheet piles)
The story of the French Messempré mill site goes back to the beginning of the 19th century when Forges Boutmy was founded. The presence of many forests in this area, along with a water reserve convertible into electrical power,
made it an excellent location. Right from the end of the 19th century, Messempré was already widely renowned for its specialty: the famous "blue" steel sheets of the Ardennes. However, the destiny of the site lay elsewhere after the
company De Wendel acquired it in 1912 and took it on a different industrial course: the production of thin steel sheets. Thereafter, industrial development played its part finally leading to the cold-forming of steel sheets in 1954, and later to the cold-forming of steel sheet piles as of 1955. Several changes of ownership occurred over the years leading to the setting up of Palfroid in 1995. ProfilArbed was in charge of sales until 2001, year where Arbed, Aceralia and Usinor merged to create the No. 1 of Steel: Arcelor. Since the creation of ArcelorMittal in 2006, ArcelorMittal Commercial RPS manages the sales of the cold formed sheet piles. The company has been ISO 9001 certified since 2004 and its products comply with European Standard EN 10249, Parts 1 and 2. Messempré mill is currently the European leader in terms of cold forming steel sheet piles
Differdange | Luxembourg (beams and piles)
The Grey mill at ArcelorMittal Differdange holds several world records, including that for the first beam measuring one meter high (in 1911), the beam with the heaviest metric weight (1,370 kg/m) and the largest beam (1,100 x 400 mm). The “QST” or quenching and self tempering process has resulted in the production of a new generation of exceptionally high quality HISTAR® beams. Combining high yield strength with excellent toughness and welding properties, they have made Differdange famous throughout the world, and are used in the construction of drilling platforms and multi-storey buildings.
Grey mill beams are being used for the most prestigious projects currently under construction, including the Freedom Tower in New York and the World Financial Centre in Shanghai. ArcelorMittal Differdange also produces the biggest HZM sections to form the most competitive high modulus combined wall systems. The group offers comprehensive coverage of rolled products, including the European IPE and HE ranges, as well as profiles which comply with American, British and Japanese standards.
