Granite Surface Plates are manufactured to BS-817 (2008) from selected inspection grade granite, chosen to provide high quality surface plate. The adjustable stands are manufactured from heavy duty angle and reinforced for rigidity. They are designed to support the plates and have levelling screws to allow the plates to set accurately. Granite Surface Plates With Stand are wildly used for precision gauging, inspection, layout and marking purposes and preferred by research laboratories, engineering industries, factory workshops, precision tool rooms, etc.
OEM or ODM Service: we offer a wide range of services from standard surface plates to custom order as per request.
Calibration Certificate: EX-works inspection reports with measurement values offered by our Quality Inspection Department are included with every surface plate, “Calibration Certificate” is available upon request for an additional charge.
Delivery Costs: calculated during the checkout process.
