Our Company



At the SDI Flat Roll Group Columbus Division, we’re committed to environmental quality and being a good corporate citizen. This commitment is reflected in our health, safety and environmental policies, our key values and our initiatives. We share the common goals of safe and healthy working conditions, pollution prevention, conservation of natural resources, reduction of greenhouse gases and the implementation of effective waste management. We adhere to all environmental regulations and seek to use the best available environmental technology.

We believe that to make the steel America needs, we don’t have to incur an ecological debt that will be repaid by future generations.

Mini-mill technology

SDI is at the forefront of mini-mill technology, a method of steelmaking that uses primarily scrap steel from a variety of sources—end-of-life automobiles, industrial equipment, infrastructure—to make new prime steel. In fact, the mini-mill segment of the American steel industry is one of the largest recyclers of metals in the nation, reusing material that once filled junkyards and littered the countryside.

Mini-mill technology has been an environmental triumph, requiring far fewer finite natural resources and significantly less energy to produce steel than the traditional integrated method of steelmaking. And because we use fewer natural resources and less energy to make steel, the ecological footprint we leave is much smaller.

U.S. Green Building Council

SDI is also a member of the U.S. Green Building Council, and our customers can earn LEED (Leadership in Energy and Environmental Design) credits by using many of our products.

In everything we do, we remain mindful of protecting our environment, striving to ensure a sustainable future for generations to come.
