The group is actively involved in offering the energy industry a complete range of products and solutions relating to each step of the energy lifecycle, from production to transformation and transport. At Hannover Messe the group presents – among other products - the latest developments of long and flat steel products for renewables such as as wind energy.

Securing safe energy supply is one of the key issues and will have a major bearing on the growth and success of developed countries. The steel industry contributes actively in saving CO2 emissions with lightweight steel solutions. ArcelorMittal delivers steel to support renewable energy use.

Sustainable long steel...

Lattice towers are ecologically attractive, being the most cost-effective solution to reach the greatest heights. Especially for on-shore applications, reaching great heights allows increased wind speeds to be utilized improving efficiency and turbine power. The low cost structure, reduced foundations combined with a corrosion protection through galvanizing makes it the best investment over the long-term.

Lattice towers made of steel have numerous advantages compared to other materials: they are at least 20% lighter, require 60% less foundations, they are easier to deliver in restricted areas (hills, forest) and they have the lowest life cycle costs for sustainable energy production.

...and flat steel products to produce wind energy

With wind towers using up to 180 tonnes of heavy plate and hundreds of individual towers in a wind farm, the logistics of ensuring just-in-time deliveries of steel are critical for success.
ArcelorMittal’s global footprint enables us to meet the needs of some of the leading players in this market – wherever they are located. Our heavy plate is used to construct both the tower and, in offshore installations, the jackets that keep the turbine stable on the sea floor. ArcelorMittal is also working with wind turbine developers to create the next generation of towers which are lighter and do not require welding.

We also supply electrical steels for the medium and high-power generators which sit at the top of the wind tower. These steels possess all of the required magnetic properties to maximise the amount of energy each turbine can produce. Offshore wind towers require weldable structural steels which can withstand the corrosive marine environment.
ArcelorMittal has a number of grades which have been specifically designed for this application. Our steels for offshore structures offer improved workability and weldability. They can be utilised in applications such as platforms and equipment for new fixed wind towers.

Come and visit us at Hannover Messe from 8 to 12 April 2013, hall 13, booth B10.
