Arcelor

Arcelor was a Luxembourg-based multinational steel producer created in 2002 by the merger of three European steel groups: Arbed of Luxembourg, Aceralia of Spain, and Usinor of France. The combination aimed to create a vertically integrated European steel company with a diversified product portfolio and a broad geographic footprint.

The company produced a wide range of steel products, including flat rolled steel such as hot rolled and cold rolled coils, coated steels, as well as long products and plates. Its customers spanned multiple sectors, notably automotive, construction, packaging, and energy, with production facilities and distribution networks across Europe and beyond. Arcelor maintained a significant presence in Western Europe and operated several major steelmaking and finishing plants, research centers, and service centers to support its integrated supply chain.

In 2006, Arcelor merged with Mittal Steel to form ArcelorMittal, the largest steel producer in the world at the time. The merger brought together Arcelor’s European footprint with Mittal Steel’s global operations, creating a multinational group with extensive production capacity and a global customer base. Regulatory review by bodies such as the European Commission led to approvals conditioned on certain divestments to maintain competition in specific markets; the combined entity later adopted the ArcelorMittal name and branding.

Arcelor as a standalone company effectively ceased to exist after the 2006 merger, with its operations continuing under the ArcelorMittal umbrella. The Arcelor name remains linked to the historical values and assets of the pre-merger group and is sometimes referenced in historical or corporate contexts regarding the European steel industry.
