Why us

FRH uses the top-quality black granite in the world to make the precision granite surtace plate with stand.
Our superior black granite has the extremely low coefficient of water absorption, so it can minimize the possibilty of your precision gages rusting while seting on the plates. This black granite creates little glare resulting in less eye strain for individual using the plates.
We have chosen our superior black granite with the specific intent of keeping thermal expansion to a minimum.

Custom requirements
The custom option is available.
UFRH can make the granite plate according to your specific requirements, we also can help you imporve the drawing for your project, including custom sizes, thicknesses. If you need to add holes, counterbores, threaded or solid stainless steel inserts, dovetail slots and t-slots to vour surface plate, we can do that as well.

All our granite products are processed and tested under the strict standard before delivery, the tolerance of flatness is 1.6 um.

Case

Our granite plates passed the test of Shenzhen Academy of Metrology & Quality inspection, HUANAN TEST, South China National Centre of Metrology, etc.

This is the 4m*3m granite mechanical component of rail detection equipment for CRRC Corporation Limited (CRRC)

We  won the tender of 8m*2.5m granite mechanical component of The Institute of High Energy Physics of the Chinese Academy of Sciences
