founded Mill Steel in 1959 with little more than a basement desk, a phone, and a belief that superior service and integrity would lead to success. Fifty years later, Mill Steel is one of North America's premier flat-rolled steel suppliers. And while Harry's son, David, now is leading the company, we continue to grow by sticking to our founding principles: Reliability. Accountability. And doing what we say we will, and then some. We´ve organized our company around those values, investing in new technologies and markets, along the way.
