Recent expansion at Diamond Headquarters in Wyoming, Pennsylvania

We just opened our new 30,000-square-foot facility. This took a lot of planning and will allow us to set up additional machines that are even more efficient and productive than before. Dave Simpson, president of Diamond Manufacturing, did the honors of cutting the ribbon in the opening ceremony of this much-needed space. We look forward to providing you with the best perforated metal to your exact specifications and offering you value-added services that take you from start to finish at an affordable price.
