Pen Manufacturing is a premier metal fabricator in Southern California. We fabricate projects of all sizes and scopes here in our Anaheim facility, shipping them out ready for assembly or installation. Many of the metal fabrication projects we do involve the construction of structures such as enclosures, platforms, test equipment, structural frames, staircases, or components, such as housings and fairings, or whatever the customer's drawing, concept, or CAD file may call for.

Metal Fabrication Company

Steel fabrication and machine shops have overlapping capabilities, but custom metal fabrication shops generally concentrate on the metal preparation, TIG welding, and MIG welding and assembly aspect while the machine shop is more concerned with the precision machining of parts. Metal fabrication at Pen Manufacturing is in a unique position because we have extensive experience in the welding and fabrication field and at the same time have considerable experience making precision machined parts. 

Pen Manufacturing possesses metal fabrication capabilities to assist your custom supply chain processes. We are able to handle large quantity jobs without sacrificing quality. Let us contribute our decades of experience to your custom supply chain manufacturing process, utilizing our resources including our Anaheim-based fully-fledged fabrication shop. Combining our staff's concepts and skills in precision machining and welding for the metal fabrication industry, Pen Manufacturing is able to help alleviate even the most difficult supply chain challenges.
