About Us The Ohio Plastics Story

OSI PLASTICS, formerly known as the Plastic Division of Ohio Steel Industries, was established in 1975 in response to extreme demands and supply shortage in the marketplace for plastic pipe. Our facilities and entrepreneurial spirit afforded us the opportunity to broaden our production capabilities and to apply our managerial and engineering strengths across a more diversified and broader base of customer, industry and marketplace. The diversity of our businesses provides us a competitive purchasing advantage and cost efficiency, which affords us cyclical and seasonal stability over the traditional, nondiversified organizations.

Since 1975, our expertise, production facilities, capabilities and our processes have developed and evolved in response to changes in the plastic industry and the marketplace. In celebration and recognition of our development and growth, and to better define our plastics business, we established and renamed our plastics division to OSI PLASTICS.
