Cast iron surface plates have been used for decades across a wide range of industrial applications. One of the main advantages is durability. Cast iron is well known for its ability to withstand heavy loads without deformation, making it suitable for machining and fabrication work. In addition, its natural damping characteristics help absorb vibrations, which may support improved measurement accuracy.
However, cast iron surface plates also have limitations. Although they are typically less expensive than granite surface plates, they are prone to rust and corrosion if they are not maintained properly. As a result, lifespan may be affected and frequent upkeep may be required. Furthermore, cast iron plates require regular scraping to maintain flatness, which can be time-consuming and may require experienced personnel.
Granite surface plates are increasingly popular in modern manufacturing and inspection applications due to their many benefits. A key advantage is granite’s inherent resistance to environmental factors such as moisture and temperature variations. Unlike cast iron, granite does not rust or corrode, supporting long-term use.
Granite surface plates also provide superior flatness and stability compared with cast iron counterparts. Their manufacturing process enables high precision and accuracy, which is critical for demanding measuring tasks. Granite also offers high hardness, contributing to durability and reduced wear over time.
On the downside, granite surface plates can be more expensive than cast iron alternatives. They are also comparatively brittle, meaning they may chip or crack if subjected to extreme impact or stress. Therefore, careful handling is required to help ensure long service life.
Ultimately, the choice between cast iron surface plates and granite surface plates depends on your specific applications, budget, and maintenance preferences. If you need a robust plate for heavy loads and can manage additional maintenance needs, a cast iron surface plate may be the best fit. If you require high accuracy, reduced maintenance, and excellent longevity, a granite surface plate may be more suitable.

Tailored Sizing for Every Scale of Operation
Micro-Precision & Bench-Top Use (200x200–1000x1000 mm)
Designed for electronics, watchmaking, and medical device manufacturing, these compact cast iron surface plates provide a stable standard for inspecting small components such as connectors and gearboxes. Their fine-ground surface (Ra1.6–3.2 μm) and 0–1 class precision (flatness ≤0.02 mm/1000 mm) are intended to support micron-level accuracy. In addition, the lightweight design (15–50 kg) helps with integration into lab benches or near CNC machines for inspection.
General Engineering & Modular Setups (1000x1500–2000x3000 mm)
As a core solution for mechanical workshops, these mid-range plates are well suited for verifying medium-sized parts—from automotive engine blocks to hydraulic valves. With ribbed undersides, they support static loads up to 2000 kg/m², making them suitable as steel fabrication tables for welding fixture alignment or CNC machine calibration. Optional T-slots (ISO 2571 standard) and threaded holes (M8–M24) improve adaptability and enable quicker clamping of gauges, fixtures, or laser alignment tools.
Heavy-Duty Industrial & Oversized Projects (2500x4000–4000x8000 mm)
For aerospace structural components, heavy machinery frames, or shipbuilding parts, our largest cast iron base plates are built to provide uncompromising rigidity. Thickened edges (50–80 mm) and dense HT300 material are intended to resist deformation under 3000 kg+ loads. Stress-relief annealing (heated to 550°C for 4 hours) helps eliminate internal tensions, supporting flatness stability even in high-temperature workshops. These plates are often used as permanent installation bases for coordinate measuring machines (CMMs) or robotic welding cells to support reliable reference measurements.
