Crown Windley Cast Iron Products


Eley Metrology's cast iron products have been manufactured for almost 100 years through the Crown Windley brand. Eley's Cast Iron product range covers all needs from surface plates to box angle plates. With the ability to produce custom products we can accommodate customer requirements in all fields.

Cast Iron Surface Plates

With a top face finished to BS 817 (2008) and available in 2 grades (1 and 2) they can be used in an inspection laboratory, tool room environment and workshops for preliminary inspections. These plates are made from well-aged, hard, close-grained iron. All of our cast iron surface plates are supported by UKAS certification. Cast iron plates are ideal when heavy items will be on the plate for example in industries such as forging and heavy manufacture.
