2 Hot Rolled Steel Sheet Piles - Rodange, Luxembourg ArcelorMittal, the worldwide leader in steel sheet pile production and foundation solutions, assessed ears ago that the introduction of its new sections, combined with the efforts to develop new markets and new applications, would lead to a significant increase of steel sheet pile demand. The first step was to dedicate its Mill 2 in Esch-Belval exclusivel to the production of steel sheet piles. Nevertheless, even pessimistic forecasts showed that the rolling capacit would reach its limit quickl. Consequentl the investment in a revamp of Mill A in Rodange, specialised in rails, rebars and special sections, was a responsible decision to increase production capacit of steel sheet piles in the short term. The renovation of Mill A is expected to be finished before the end of Based on its unique experience gained in Esch-Belval, ArcelorMittal is quite confident that b beginning of 2008, the first industrial rolling of steel sheet piles in Rodange will take place. The mill will still continue producing the other products. This revamp ielded the opportunit to optimize the shapes of existing sections. The renewal of the low range of U-tpe sections was developed in collaboration with the R&D department. Three new PU-R sections (with rolled-up and down profiles) will be available in a first phase. The sections are 600 mm, respectivel 675 mm wide, and are intended to replace the existing PU 6, PU 8 and PU 12 produced in Belval, whose production will be discontinued beginning of Furthermore the merger of Arcelor and Mittal in 2006 added another mill manufacturing steel sheet piles to the group. Located in Dabrowa, Poland, it produces three different U-sections. For more information, please contact our local representative, or our headquarters, and visit our website for latest updates.
