Today, Marcegaglia, at its plant in Ravenna, Italy, the main manufacturing unit dedicated to flat carbon steel and the intermodal logistic hub of all group’s activities, is aiming at increasing the production of hot-dip galvanised dual-phase DP600 steels, manufactured in accordance with EN 10346, and, with its internal R&D team, on the higher grades DP800 and CP800. These steels allow vehicle weight reduction, actively contributing to carbon dioxide emission reduction (as regulated by the EU), while guaranteeing maximum safety. The hot-dip galvanising process also allows higher durability in terms of corrosion resistance and better performance in the long-term. Marcegaglia: flat universe Today Marcegaglia has a well-established presence in the flat steel products sector (both carbon and stainless steel), including the manufacturing of heavy quarto plates and pre-painted products. It is a key international player capable of supplying not only other service centres but also specialised customers with a wide range of products in terms of steel grades and applications: a unique range of services with quick response times thanks to its stock availability in standard sizes. Magnetic steels: new semi-processed grade M310-50K Today, the R&D in the magnetic steels field is focusing – both for GO (grain-oriented) and NGO (non-grain-oriented), which represents about 80 per cent of the market – on improving the efficiency of electrical motors by selecting materials with high magnetic properties. This is a result that can be attained only through the optimisation of the entire manufacturing process: from hot rolling to cold rolling and skin-passing steps. Accordingly, Marcegaglia presented, during the “7 th International Conference Magnetism andMetallurgy WMM ’16” the development of the new grade of semi-processed magnetic steel M310-50K, based on a 2.0 wt% Si non- oriented magnetic steel through the optimisation of the microstructural characteristics of the semi-finished product by means of the thermo-mechanical processing (TMP) conditions and the following cold rolling, annealing cycle and skin-pass processes. Microstructure and ODF analyses were carried out on samples that were hot rolled, cold rolled and annealed, and after final decarburisation and secondary recrystallisation annealing. The results of the case study confirmed that in order to develop favourable textures and to achieve the target magnetic properties a thorough approach for the whole production chain has to be adopted.

Pre-painted steels: two new finishes for unique aesthetic levels with steel safety In the pre-painted steels sector, Marcegaglia is developing new finishes with high aesthetic qualities giving efficiency and durability, along with the safety of the steel itself. This is the case, for example, with the brand-new product that simulates wood surfaces – in three colours and finishes – through a process of painting and finishing directly on steel. It is an innovative coating that can be used for several applications, especially in the field of architecture, that combines the aesthetic value of wood with structural steel materials and their mechanical properties. The exclusive brand-new polyester resin coating system SHIMOCO (free of hexavalent chromium and heavy metals) is formulated to allow the best UV and corrosion resistance, guaranteeing maximum flexibility and durability, while having sophisticated and intrinsic aesthetic qualities thanks to the composition and textural pattern of the paint itself. Last but not least is the efficiency of the distribution network connecting the manufacturing plants with each other and with customers: 11 logistic intermodal terminals (or hubs) strategically located in harbours on the Mediterranean Sea, the Atlantic Ocean, the North Sea and the Baltic Sea, as well as storage areas near important railway connections, significantly cutting delivery times as well as carbon emissions, and enhancing flexibility and service.

Thanks to these features, it is particularly suitable for roofing applications and also for cladding and façades.
