Granite Surface Plate

JASH Granite Surface Plates are used for precision gauging, inspection, layout and marking purposes. They are preferred by Precision Tool Rooms, Engineering Industries and Research Laboratories because of their following outstanding advantages.

No rust, no corrosion, relatively warp-free, no compensating hump when nicked, longer wear, smoother action, greater precision, non-magnetic, less care after commissioning, lower co-efficient of thermal expansion and non-glaring surface. These features make JASH one of the best granite surface plate manufacturers in the industry.
