About John Cockerill
John Cockerill is a Belgian industrial engineering group headquartered in Seraing, Liège province, with roots going back to the early nineteenth century in the Liège steel basin. Its activities cover equipment and services for steel plants, energy, defence and industry, rather than steel production itself.
In the steel sector, the group designs and supplies processing lines, reheating furnaces and maintenance services for steelmakers, drawing on a long history in the Walloon metallurgical industry. Its energy business covers hydrogen, solar and industrial decarbonisation solutions, while its defence arm produces turret systems.
John Cockerill's identity is tied to Seraing, where its historic site remains a symbol of Belgian industrial heritage. For the construction and materials sectors, it is a technology and equipment supplier to the steel industry, not a mill, and its record is included on that basis.
