This is Precision

Since 2005, GLC has been an integral and seamless extension of our customers’ machining, turning, milling, and robotic welding operations. With unmatched quality and competitive pricing, we boost bottom line returns and increase productivity across the enterprise.

We handle the most complex product specifications to meet the highest consumer expectations – a true partner in success. Precision and value are the heartbeat of GLC.

A strong and experienced team of machinists and problem-solvers use state-of-the-art CNC milling and turning centers to machine build-to-print products from all metals and routinely hold half-a-thousandth tolerances.  In-house robotic welding and strong supply chain partners in heat treatment and plating increases value-add service.  GLC serves numerous commercial and government customers and operates as an AS9100D and ISO9001-2015 certified company with mature manufacturing and business processes.  Customer service is in our DNA. In 2022, the GLC team proudly machined a satellite chassis that was launched aboard SLS Artemis 1 mission and deployed to the moon.

ISO 9001:2015

GLC has one vision: to be the premier job and machine shop in the nation. We proudly serve customers across the private sector and government agencies. As of November, 2017, GLC’s Quality Management System is officially certified by Eagle Registrations Inc. to conform to AS9100D including ISO 9001:2015 Standards.


GLC offers high-quality products and processes to solve our customers’ most difficult problems. Through our commitment to excellence, capability, responsibility, and partnership, we exceed our customers’ expectations every day.


At GLC Industries, we understand that your machining needs won’t always fit into the typical machining shop’s comfort zone. Through experience with fixtures, jigs, prototypes, preproduction, and production run machining, our capabilities far surpass the industry standard. With technical expertise to expand as our customers’ needs change, we can remain a constant partner, growing alongside you as your business needs expand.

Robotic Welding

GLC Industries has successfully incorporated robotic welding into many of our processes. Our manufacturing capabilities include an OTC 2 station, 7 axis digitally controlled Metal Inert Gas (MIG) weld robotic cell. This weld cell gives GLC the ability to manufacture a wide range of components in medium to high volumes, while repeating close tolerances part after part. Our versatility and quality precision allow us to consistently exceed customer expectations.


GLC provides GMAW (MIG Welding), GTAW (TIG Welding), and FCAW (Arc Welding) processes in low to medium volumes with capabilities in ferrous and non-ferrous material up to 1″ meeting AWS standards. These processes are achieved in an environmentally controlled booth.

    The GLC team is very proud of this achievement and looks forward to contributing this level of quality management standards to all existing projects and toward future success for our valued customers!

  • GLC Industries Keeps the USAF Premier

    After 40 years of service, many of the original specifications and drawings for the A-10 were either obsolete, or missing. On top of that, most of the supply chain was no longer available. To ensure its ability to sustain the aircraft, the USAF had to find and qualify new sources for specialized maintenance equipment and tooling.

    GLC’s engineering and manufacturing teams reviewed available drawings and specifications and determined that with the use of new technology and modern materials the tooling could be reproduced faster, and at or below previous costs to the USAF. To date, GLC has either reproduced, re-engineered, or reverse engineered numerous items in support of the A-10 Thunderbolt.

  • GLC Industries Delivers Critical Look

    Following the revision of the federal specification for Electromechanical Combination Locks (FF-L-2470), GLC’s Customer initiated changes for its X-series High Security Lock to ensure compliance with the Government’s highest security standard. The Customer awarded GLC a contract to manufacture components for the prototype high security combination lock. Following a number of changes and component revisions, the Government tested and approved the security lock under federal specification FF-L-2740.

    GLC worked closely with buyers and engineers to fabricate the high precision machined components required to meet the exacting Government specifications and testing. GLC’s on-time delivery, quality processes, and responsiveness to the Customer’s need were key to the success of this project and ultimately the award of a Government contract to our Customer.
