The Largest & Most Experienced Precision Granite Manufacturing Team in the US
OVER 60 YEARS OF EXPERTISE
When performance, accuracy, and reliability are critical, the structure behind your system matters. Tru-Stone engineers and manufactures precision granite machine bases, surface plates, metrology accessories, and integrated structural solutions that provide the stable foundation high-precision equipment depends on.
Whether you're developing a new system or improving an existing one, you'll have the engineering support and manufacturing expertise needed to create a precision granite solution tailored to your application's performance requirements.
Precision Begins with the Right Foundation
The performance of any precision system starts with the material it's built on. When measuring at the micron or sub-micron level, the base structure is just as important as the measuring equipment. Precision granite provides exceptional stability and vibration isolation, allowing measurement equipment to achieve greater accuracy and repeatability.
That's why engineers choose precision granite for metrology, motion control, semiconductor, optics, photonics, and other high-precision applications where consistent performance is critical.
