A decade later, in 1977, as a result of the constant commitment to innovation, the first electric fusion furnace was inaugurated in Sant Andreu de la Barca, Barcelona.

From this moment on, the company stops transforming products for third parties and begins to manufacture steel autonomously, allowing it to increase its production and market share.

With the entry of the new millennium, the company’s international expansion begins through the creation of CELSA Steel UK in Cardiff, United Kingdom, and CELSA Huta in Ostroweic, Poland. The success of both operations is the triggering factor of a globalizing process that is beginning to take shape and consolidate.

CELSA expands its international projection with the creation of CELSA Nordic, made up of various processing companies located in different countries in northern Europe, and CELSA France, located in Bayonne. Not only that, a year later, we expanded our presence in the United Kingdom and Ireland with the acquisition of BRC, ROM Group and Express Reinforcements.

Sustainable development and excellence in environmental management are two fundamental pillars for the Group. Through a sustainable work dynamic based on innovative and efficient recycling techniques, CELSA Group™ has become a benchmark for the circular economy.

Steel faces new challenges and with it new opportunities. In our commitment to lead the transformation of steel and industry 4.0, we continue to make progress in the digitalization of the supply chain to maintain excellence in the sales and operations planning process, also in “lean” services. construction” to help our customers be more efficient and sustainable.
