Welcome to Great Lakes Testing

About Us


    We are Great Lakes Testing (GLT), and we strive to provide quality while performing Non Destructive Testing. We perform Radiographic Testing, Magnetic Particle Testing, Dye Penetrant Testing, Ultrasonic Testing, Pressure Testing, and we also have our Fire Division in which we perform tests on the ladders for fire departments.


    As of 2013, we also offer CR (Computed Radiography) for castings. With this, you recieve a disc instead of film, and operates on a computer.


    We have also expanded and opened up a shop in Neenah, WI. With this expansion, we also have a CR located here, and allows us to operate out of the Neenah location.
