From product development to field service, our team handles every step in-house. Engineering, controls, manufacturing, and service all live under one roof in Dayton, Ohio. The same engineers who design our gauges support them in the field.
Five leaders running operations, sales, finance, and strategy from our Dayton, Ohio headquarters.





PLC controls, product development, electronics, and mechanical design, all under one roof.








Production, quality, materials, and the field service technicians who travel to mills worldwide.









Most engineering and field staff joined GGC after years inside steel, aluminum, or coating mills. We hire for instinct, not just credentials.
Our leadership team built their careers in measurement and instrumentation. We invest in long-term career paths, not roles to fill.
Engineering, manufacturing, and service all live in Dayton. The teams talk to each other every day; there is no offshore handoff.
We hire when we find the right people, not when a role opens. Send your background and what mill problems you have solved, we will respond within five business days.
