Competence

We own and operate quarries throughout the US and Canada giving us the pick of the best granites for precision and industrial products. The high quartz content of our Barre Gray and Salisbury Pink granites make an extremely hard surface with excellent wear characteristics and low porosity. Our high density American Black granite has both a low absorption rate and a low coefficient of thermal expansion making it ideal for precision machine bases.For mounting points we offer threaded inserts on position, dovetails in the granite, or inserted steel bars with T-slots. All our surface plates meet or exceed ASME Standard B89-3-7 2013 and Federal Specification GGG-P-463c. Our standard and custom metrology components include master squares, master angles, parallels and straight edges. All include a NIST traceable calibration certificate.
