Introduction Long Carbon Europe product range Wind energy Solar energy Biomas power plant Related markets Finishing Sustainability Product summary Technical documentation

Fossil fuels run out Energy is one of the major drivers of economies. Securing energy is one of the key issues and will have a major bearing on the growth and success of developed countries. Oil and gas supplies are dwindling, and their use is becoming increasingly expensive, while nuclear energy is becoming increasingly controversial. The rising prices of electricity, oil, coal and gas and the problem of future energy supply are now in the consciousness of the general public. The public debate on climate change, environmental disasters and emissions trading is also widely covered in the...

Wind energy requires specific and reliable foundation solutions adapted to high loads and dynamics but also reducing the total environmental footprint of the foundation. Therefore ArcelorMittal offers and delivers : HP bearing piles: well suited to use in cases where very soft clay or loose sand and gravel is present in the soil. Ranging from HP 200 x 43 (42,5 kg/m) to HP 400 x 231 (231 kg/m). Rebar: available in every country with national certification in a range from 6 mm to 50 mm. SBQ (Special Bar Quality) and threaded bars: available in carbon grades, low and high alloy grades in...

Lattice tower Rediscovery of a proven design Lattice tower wind turbines seemed to have been almost crowded out by the tubular tower, but they have experienced a renaissance in recent years. They are ecologically attractive, being the most cost-effective solution to reach the the greatest heights. Especially for on-shore applications, reaching great heights allows increased wind speeds to be utilized increasing efficiency and turbine power. Additionally, wind shear decreases with height, thus fatigue stresses are reduced as well. The design provides a reduced frontal area, optical...

; highest wind farm in the world (141 m) ArcelorMittal holds a leading position with L300 in non-alloy structural steels and thermomechanically rolled steels (according to This combination of profiles and grades brings increased stiffness to reach the greatest heights, specifically for those between 100 As shown in figure 5, the use of a very wide angle can significantly reduce the weight of a lattice tower submitted to the highest loads. The benefit can reach 34% of weight reduction reducing not only the total material cost but also the total fabrication cost. Using a wide angle reduces...

Solar technology makes use of the daily incoming solar energy, the socalled «global radiation». Both heat and power from the radiation can be harnessed. Today we can collect the sun’s energy with two different methods: with photovoltaic cells or with collectors heated by the sun. Solar power plants require various long products. Planning principles of Substructures Speed of construction and thus investment costs can be particularly reduced by pre-assembly. The use of long products makes an essential contribution. Due to the various available profile dimensions the design can be optimized...

5. Biomass power plants Technical assistance For years, ArcelorMittal Long Carbon Europe has being developing partnerships in power plant buildings. Our technical teams are supporting engineers in the design of structural elements, construction details, surface protection, fire safety, metallurgy and welding processes. Specific steel grades Histar Over the years, through this expertise we introduced new products such as Histar® steel grades combining high yield strength with excellent toughness at low temperatures and outstanding weldability. For the same bearing capacity, Histar® 460 High...
