Company History
Founded in Los Angeles in 1956 by David C. Hall, Diamond Perforated Metals, Inc. was the first major manufacturer of Perforated Metals on the West Coast. In 1962 Diamond added expanded metal manufacturing to its capabilities. In 1988 Diamond acquired California Perforating Screen, a competitor, giving us additional capacity and employee experience. In 1994 Diamond consolidated the two operations and built a new perforated metal manufacturing plant strategically located in Central California. This new facility was designed from the ground up to efficiently produce the best quality perforated materials in the industry. In it are the most modern perforating presses and support equipment available today.
Diamond built its reputation based on Mr. Hall’s obsession with pleasing the customer and building lifelong relationships. This still holds true 50 years later. With this business foundation, Diamond Perforated Metals has grown to become one of the largest manufacturers and distributors of perforated and expanded metal in the United States, with locations in Visalia and Los Angeles Ca., Seattle, Denver, and Chicago offering same day shipments!
