Granite Surface Tables


The ideal material for metrologist:

  • Non reflective
  • Non magnetic
  • Low Maintenance
  • Low co-efficient of expansion
  • Can be worked to extreme precision
  • Granite does not rust and has a high resistance to other forms of corrosion
  • If the surface is damaged, the surrounding area is unaffected and the surface's accuracy is not impaired
