EMESA is a company that belongs to Grupo SOIL, specialising in engineering, manufacturing and assembly of solutions on one-off metal structures, and with a lengthy history in the renewable energies sector, in the production of wind towers and components for the solar industry and bio-fuel plants. Our capacity to develop highly complex engineering projects and solutions has turned us into an international benchmark, ensuring the highest levels of competitiveness, quality and customer satisfaction.

Our VISION is to become a leader in solutions of one-off structures in the wind sector, whereby our major mission is to achieve the highest levels of quality, integrity and competitiveness, ensuring a safe environment and helping to advance and develop our environment. We aim to achieve the highest levels of customer satisfaction, offering leadership based on qualified employees, cutting-edge technology and acting with integrity in everything we do.

The company Elaborados Metálicos Emesa was incorporated in A Coruña on 31 March 1958. The corporate purpose was to obtain steels using an electric furnace; the production and transformation of metal alloys in general, and metal fabrication, forging, drawing out and stamping of metals and alloys. Emesa started out. Emesa was committed to developing its own technology and set up the laboratory for mechanical and chemical testing, which would achieve huge success in the development of high resistance cables and wires. Emesa achieved international recognition with these products, which exceeded the features of any others available in the market.

During the 1960s, the company’s activity started to move away from iron and steel activities and towards the construction of metal structures. In 1971, the metal constructions department acquired two 20-tonne bridge cranes that were capable of taking on any works at that time. With this, Emesa has one of the best equipped workshops in Spain. This means it can tackle not only larger jobs, but also increase the company’s technical contribution to projects. The construction and assembly of the metal surface of the Rande Bridge – which, with its 400-m span, was at the time the largest cable-stayed bridge in the world – was a decisive step in this direction.

For the Rande Bridge project, which was built between 1973 and 1977, the company received an award from the Spanish Association of Metal Structures and Boilermaking (Asociación Nacional de Construcciones Metálicas y Calderería) (Sercometal). That period also saw the iron and steel activity of Emesa undergo a huge change, with the wire-drawing business moving to a new factory in the town of Sabón (Arteixo). The company would also be committed to taking a stake in the set-up of Siderúrgica de Galicia, S.A. (Sidegasa), a project that would suffer the rigours of the energy crisis at the end of the 1970s and the reconversion process of heavy industry in the 1980s.

From 1975 onwards, the poor economic situation started to have an appreciable effect on the company’s progress. Emesa try to offset the weakness of the domestic market by exporting. Three years later the company stopped its iron and steel activity and the workers of that department moved to the newly incorporated Sidegasa. However, the wire-drawing business line remained at the new plant in Sabón, while the metal constructions continued at the old premises in A Coruña.

At the same time, EMESA searched for and found a new business line in the construction of components for the wind energy sector, which has become one of the company’s mainstays. In 1995, EMESA built its inaugural shafts for wind turbines, to be used at two wind farms in the province of A Coruña.

In 1999, EMESA joined the Isolux-Corsas group and began the transfer process which would end with the set-up of the modern CCC plant. The coming-into-operation of the new facilities, with a total surface area in excess of 100,000 square metres took place in 2004 and represented a major leap forward for the company in terms of production capacity, adjustment of costs and improvement of quality. All this has enabled Emesa to consolidate itself as a leader in the construction of singular metal structures and production of components for the wind and photovoltaic sector. In 2006, the company’s production capacity reached 45,000 ton/year, of which 20,000 tonnes correspond to structures and 25,000 to products for wind and photovoltaic facilities.

In October 2015, Grupo SOIL acquires 100% of  EMESA.


Emesa has its headquarters and factory on the CCC Business Park, just 30 km from the high-capacity ports of A Coruña and Ferrol. The company has modern premises, which opened in 2004, with 32,000 square metres built on a plot of 109,000 square metres. The movement of large structures is facilitated by our excellent communication with the A-6 dual carriageway and the AP-9 motorway.
