Full Service Custom Metal Fabrication, Machining & Assembly

Regardless of the complexity of the project or process, only craftsmen specifically trained on the customer product participate in its fabrication. Quality is checked after each process and again prior to shipping. A complete history of the product from material and source to fabrication notes and previous fabrication runs is kept with the product on the floor at all times. “Re-orders” follow the same process, with print revisions verified prior to beginning any work. Our customers appreciate that we understand the costs and headaches associated with “high maintenance” vendors and we are committed to ensuring Hallmark is never high-cost. As a result of our customer service and history of on time per-print fabrication, our customers are now choosing to reduce or eliminate their typical inspection and handling costs by taking Hallmark product directly into their manufacturing/assembly floors.
