Major Metals Company was incorporated in Ohio in October, 1973 to consolidate the trading activities of its founder, Jack Mason. This included buying and selling all types of steel products and processing steel via contract manufacturing. The use of widely varying sources of material to supply a broad customer base has kept the company prosperous in an extremely cyclical industry. 

In the mid 1980's Jack Mason began withdrawing from the day to day activities. His final retirement resulted from a buy out agreement with his son, Jeff Mason dated January 1, 1985. 

In June of 1992 the company purchased two welded steel tube mills.  An 8,000 square foot building on Kochheiser Road in Mansfield was purchased in December, 1992. The first tube mill was in production in August, 1993.
