Industeel, the specialty steel arm of ArcelorMittal, supplies high-specification steel plates for the Sagrada Família basilica in Barcelona. The iconic church, under construction since eighteen eighty-two, is targeting completion of its final towers this decade. The central Tower of Jesus Christ will reach one hundred and seventy-two point five meters, becoming the world's tallest church. Industeel's plates meet exacting structural standards for strength, toughness, and weldability, enabling the complex geometry of Gaudí's visionary design to be realized at full industrial scale.
