For over a century, Diamond Manufacturing has led the way in the perforated metals industry. As the nation’s premier perforated metal specialists, we have been the industry leader in adopting new technologies, implementing the most modern equipment, opening up new markets, and attracting the finest, most talented craftsmen.
Today, Diamond Manufacturing continues to develop and invest in the latest technology. We purchase more than 70 million pounds of steel each year from U.S. and foreign suppliers, and employ more than 380 employees in six manufacturing and stocking facilities located throughout the US.
When Diamond’s founder, John Newton Thomas, opened a small perforating plant to manufacture sizing screens for the coal industry in 1915, he probably never imagined that a century later that small shop would grow to become the largest perforator in North America and among the top five in the world.
As we journeyed through the next century, we were fortunate to have leaders with the vision and tenacity to successfully steer Diamond into the future. In the 60’s and 70’s, Diamond’s president, Charles Flack, assisted in the development of new electronic feed systems and the computerization of the perforating industry.
Flack opened up exciting new markets for the firm, leading Diamond into the aircraft and appliance industries, and the development of sophisticated pollution and acoustical controls. This included development of the domes for the Pittsburgh Civic Center and the Astrodome in Texas as well as production of the materials needed for the acoustical chambers housing the pumping equipment along the Alaskan pipeline.
