Cast Iron Surface Plates & Tables
UKAS Certified | Scraped & Planed Finish | BS 817:2008
Eley Metrology captures and continues the heritage of the Crown Windley brand (est. 1904), manufacturing cast iron surface plates from well-aged, hard, close-grained iron, calibrated with either a scraped or planed finish to BS 817:2008 in our UKAS-certified laboratory.
Why Choose Eley’s Cast-Iron Surface Plates?
- Quality Cast Iron:
We source only the finest quality iron for the cast iron metrology standards we produce. - Heavy-Load Optimised: Carefully sourced, close-grained iron handles forging and manufacturing loads, reducing distortion under heavy components where typical thinner, less suitable materials are at bigger risk.
- Scraped & Planed Finish: 120+ years of expertise, allows us to deliver exceptional flatness (Grade 0, 1 and 2) for workshop and toolroom use, with the capability of delivering both a planed and scraped finish on cast iron surface plates.
- Aged for Dimensional Stability: Seasoned material minimises expansion and contraction, ensuring consistent reference geometry in variable shop-floor conditions.
- Magnetic Work holding Surface: Ferrous construction enables secure magnetic clamping of components, and fixtures during inspection and setup.
- Workshop inspection and layout: Verify flatness, check dimensions, and scribe layout lines on components and assemblies.
- Magnetic work holding for inspection: Secure ferrous parts, fixtures, and tooling magnetically during measurement and setup.
- Hybrid measurement setups: Complements granite plates where magnetic clamping or heavier load bearing is required.
UKAS Certification: Our cast iron surface plates can be supplied with UKAS certification or Eley Metrology calibration certification to keep your surfaces traceable and inspection-ready on arrival.

FAQs
Can cast iron surface plates be repaired?
Yes. Cast iron plates can be hand-scraped or planed to restore flatness and original specification, making field repair practical and cost-effective. We offer calibration and resurfacing services onsite or in our UKAS laboratory.

How often should a cast iron surface plate be calibrated?
Typical intervals are 6–12 months for heavy workshop use, or annually for lighter inspection applications. Calibration frequency depends on use, handling, and your quality system requirements.

What are the benefits of magnetic workholding on cast iron plates?
Ferrous cast iron allows secure magnetic clamping of components, fixtures, and tooling during inspection and layout, a key advantage over non-magnetic alternatives liked granite in production and toolroom environments.
Do you manufacture bespoke cast iron surface plates?
Yes. We produce custom-sized cast iron plates to your specifications, including non-standard dimensions and fixture configurations.
