No, MetPro specializes only in post-processing cast iron castings. You supply the casting — we turn it into a finished part.

02

What cast iron processing operations do you perform?

We offer the full processing cycle: grinding, shot blasting, heat treatment, welding, painting, CNC machining and final assembly.

03

What is your level of precision?

Our CNC machines ensure ±0.01 mm tolerance. All processes comply with ISO 9001:2015 and are strictly controlled.

04

What is your capacity for maximum size and weight of cast iron parts?

We process parts up to 2.5 tons and up to 4000 mm in length, depending on the type of service.
