Product Description

•  Dense granite structure, smooth surface and nice abrasion resistance, low roughness.

•  Natural granite by a long-term aging, the interior stress disappeared, material stable, and will not be deformed.

•  Acid, alkali, corrosion resistance, anti-magnetic.

•  No damp rust, using and maintenance are easy. 

•  Linear expansion coefficient, little affected by temperature;

• Working surface is scratched by the collision, only produces pits, does not produce convexity pattern, glitch, no effect on the measurement accuracy.

• The main disadvantage of granite surface plate and platform is: can not stand over impact, knock, high humidity will be deformed, 1% moisture absorption.

• If you want T-slots or holes ,we can produce the plate according to your drawing
