Surface Plates & Support

Rock of Ages Precision Granite Products has one of the longest histories in the United States in the manufacture of granite surface plates and metrology components. Our experience has made our products some of the best in the industry. We manufacture a considerable number of medium to very large-sized surface plates for special applications, up to 50 feet in length.  For these types of applications we offer our local Barre Gray and Salisbury Pink, an especially hard and wear-resistant material.
