  • Offshore and Onshore Wind Turbines

    Eiffage Metal plays an active role in the renewable energies sector. Our Spanish subsidiary was one of the first onshore met mast constructors to take part in developing wind farms in the Iberian Peninsula. Our Belgian subsidiary Smulders has built over 1,300 steel foundation structures for offshore wind turbines, thus consolidating its position as market leader. In France, our Fos sur Mer site is diversifying its production within the industrial sector towards the renewable marine energy market, and floating offshore wind turbines in particular.

    Eiffage Metal thus offers a range of services from simple steel component manufacturing for offshore and onshore wind farms to turnkey contracts grouping together the design, manufacturing and installation of complex sub-assemblies including:

    • Offshore and onshore met masts

Our in-depth steel construction knowledge and specialist mechanical departments enable us to offer you top-quality turnkey solutions to suit all budgets and projects, from paint docks to plane maintenance.

  • Shelters

    There are many Shelter-type products on the market but they are often based on the shipping container and do not offer much latitude in terms of size or adaptability. For several years, Eiffage Metal has been developing a Shelter concept which can be adapted to large dimensions, with a metal framework, cladding and roofing. They are magnetic wave and weatherproof, air-conditioned or heated according to need and designed to resist aggressive conditions (desert or sea, for example). These products, such as electrical houses (e-houses) created for the armaments and oil and gas sectors, are designed and manufactured in our plants, then dispatched all over the world.
