We Make You Look Good

Delaware Valley Steel, located in Upper Darby, PA, is a premier steel plate supplier. Established as a full-line service center in the 1950s, we originally served local fabricators, machine shops, and OEMs in the Tri-State area. In the 1980s, under new ownership, we shifted direction and became known as the region’s top provider of burned steel plates. To support this niche, additional inventory and processing equipment were acquired. By 1985, we committed to exclusively supplying carbon and alloy plates, solidifying its reputation in the industry.

More Equipment and Products

Over the years, we have continually expanded our equipment and products to meet our customers’ evolving needs. This includes installing one of the area’s first plate saws, a car-bottom CNC-controlled furnace, and additional state-of-the-art burning machines. Today, all our burning machines are less than 10 years old and are operated using the latest Burny controllers. These controllers are linked to our server, where all CNC programs are stored. This connectivity enables us to optimally nest your parts in real-time directly from the shop floor, ensuring precision and efficiency in every project.
