Founded in 1984, G.P. Manufacturing is a family-owned precision sheet metal fabrication company serving manufacturers throughout Orange County and Southern California. For over 40 years, we have built long-term customer relationships through dependable quality, competitive lead times, and responsive service.
Our capabilities include precision laser cutting, CNC punching, CNC forming, and in-house deburring for both prototype and production manufacturing. We work with aluminum, stainless steel, cold-rolled steel, copper, and brass across a wide range of industries and applications.
Operating from Orange, California, G.P. Manufacturing combines decades of fabrication experience with modern equipment and technology, including advanced fiber laser cutting capabilities. All forming and deburring operations are completed in-house, while trusted local finishing partners provide powder coating, chem film, anodizing, zinc plating, nickel plating, silkscreen, and other secondary finishing services.
Today, under second-generation leadership, we continue to modernize our operations while staying committed to the reliability, communication, and customer support that have defined our company since 1984.
