In 1955 the Belden management showed their confidence in their company’s future by starting construction of a new plant at Sugarcreek. It would be the largest plant in the country for the production of face brick and building tile. The plant went into operation in 1957. It is now known as Plant 6. Paul Belden found Sugarcreek to be a community of fair and cooperative people. The supply of raw material was plentiful and of excellent quality. Transportation facilities were good; in addition to rail shipments there were two trucking companies that served their plants. They had a good working force, and the Company’s policies toward their employees were well received by the community.

Building upon the abundance of raw material and an outstanding labor pool, Belden’s plant No. 8 went into operation in May of 1968. It was the largest brick plant ever built under one roof. Paul Belden Senior died on February 13, 1970. He had been Chairman of the Board of The Belden Brick Company since 1946. The Board of Directors held an organizational meeting. The directors elected the following officers: Paul B. Belden, Jr., Chairman of the Board; William H. Belden, Sr., President; and Paul W. Hartung Jr., Vice President.

Directors elected at this meeting were Paul B. Belden, Jr., Wm. H. Belden, Sr., Daniel M. Belden and Richard F. Belden. Dan and Richard were the two youngest sons of Paul B. Belden Sr. In 1973 The Belden Brick Company acquired the assets, properties and manufacturing facilities of the Moomaw Brothers at Sugarcreek. The Shepfer-Moomaw plant was designated as plant No. 9 by Belden although they only had eight operating plants. Canton plant No. 1, which was the original Belden plant was closed down in June 1970. On September 12, 1974, The Belden Brick Company acquired the Strasburg Brick Company of Strasburg, Ohio. Their principal product was face brick in red and other colors. The Belden Brick Company added a packaging machine and considered adding another tunnel kiln if needed. Belden’s sales organization and agents gave Strasburg’s products a widening distribution.

In December of 1976, the following directors comprised the board of Belden Brick: Paul B. Belden, Jr., William H. Belden, Sr., Daniel M. Belden, Richard F. Belden, Paul W. Hartung, Jr., and Burke B. Wentz. Larry Myers, whose family had owned the Strasburg Brick Company, was named Assistant General Superintendent to Burke Wentz.
