The History of Leeco® Steel

Leeco® Steel maintains one of the nation's largest inventories of carbon, HSLA, and alloy steel that come from the premier mills domestically and worldwide.

Leeco Steel began in 1882 as Leopold Cohen Iron and Metal. The company’s founder, Leopold Cohen, set up shop on Chicago’s west side at 300 Kedzie Avenue South. The business spanned three generations and worked through a century of progress as it continued to strategically place facilities across the United States to better service its customers.

Leeco Steel remained family-owned until 1997 when employees partnered with an investment firm to buy the company. That group of dedicated employees ran a successful ESOP until 2005 when it was purchased by O’Neal Industries.

O’Neal Industries is a family of closely related companies, all engaged in the metals industry. Providing products and services that range from steel beams and plates to specialty alloys and complex manufactured components, and tube manufacturing, ONI supplies customers across a variety of industries worldwide. Together, our companies represent the United States’ largest family-owned metals service center.

Today, Leeco Steel continues to see success and growth. Its legacy is rooted in hard work, employee dedication and industry expertise. We now have locations throughout North America, Canada and Mexico – and we aren’t done. We are about smart growth that translates to good business that helps our customers.
