About AG der Dilliner Hüttenwerke


Dillinger is a world   leader in the manufacturing of heavy steelplates in a uniquely wide range of steel   grades, product dimensions and item weights. The steel grades range from   non-alloy structural steels to ultra-high-strength fine-grained steels and   from weather-resistant to sour-gas-resistant steels. Dillinger offers plate   thicknesses up to 500 mm and widths up to 5,200 mm. Plate weights up to 52 t are possible. The   high-tech plates are used to realize extraordinary and technically   sophisticated projects all over the globe: e. g. in the areas of steel   construction, engineering, offshore oil and gas, offshore wind and tidal power,   line pipe and pressure vessel construction, Earth moving machinery and Mining.


With a high level of   innovation, state-of-the-art production processes, valuable service offers   and – not at least – many years of experience, Dillinger provides crucial   added value to its customers. In addition to excellent product quality, we at   Dillinger have always attached great importance to cooperation based on trust   and partnership. We help our customers to better master whatever challenges they may   face: close and long-standing customer relationships bear eloquent witness to   this.


Dillinger is firmly   committed to the objectives of the Paris Climate Agreement. Our path to   carbon-neutral steel production stands under the motto “proactive,   carbon-free, efficient”. Over the last 15 years, Dillinger and its sister   company Saarstahl already made investments in the amount of EUR 700 million   to improve environmental protection and efficiency. With our “proactive,   carbon-free, efficient” strategy, we aim to be producing carbon-neutral steel   by no later than 2045. Achieving this complete transformation will require   large investments in new facilities and new infrastructure. Therefore we have to be realistic: the goal of 100% CO2 neutrality   will need time. Nevertheless, the   first steps have in fact been successfully taken and we plan to achieve   significant carbon savings already by 2035.
