The project

STEEL DYNAMICS INC. – A new dimension

In autumn 2021, the new flat steel complex of Steel Dynamics Inc. (SDI) will start operation. In Sinton, Texas (USA), SDI will produce 2.7 million metric tons of high-quality flat steel per year and the town will become the gateway of SDI for the markets of South-Western USA and Mexico.

But how does such a big project come into reality? The answer is: team work. Both within the SMS group as well as with suppliers and of course with the customer: SDI. Stay with us and follow the project from ground-breaking to the development of the site, the equipment design and manufacturing, the delivery to the US, the commissioning phase to the start of production.
