This image provides a detailed view of a surface finished by a CNC milling operation. The intricate, arcing pattern visible on the face of the thick metal block is the characteristic tool path mark of a face mill, used to create a highly accurate and flat surface. The workpiece is a substantial block of steel, and other machined features, such as a drilled hole, are also visible. This close-up effectively demonstrates the precision and quality of the surface finishes achievable with modern CNC machining on heavy-duty components.

Steel Milling for a Range of Industries

Milled parts to your exact specifications

Precision and Capability

Our factory is equipped to handle a wide range of component sizes, from smaller detailed parts through to large plates and structures. Using advanced CNC milling machines capable of handling parts up to 1620mm x 810mm, we achieve consistent tolerances and surface finishes, ensuring your parts are delivered to specification every time.

We work with standard grades such as S275 and S355 as well as specialist steels including high strength and wear-resistant steels within 3mm to 300mm thick. This flexibility allows us to support diverse applications from bridge plates and gantries through to pressure vessel components and offshore frames.

Why Choose Our Milling Service

Companies turn to RMP Products when they need more than just machining. They need assurance. Every project carries risk and we help reduce that by providing precision CNC milling backed by EN 1090 EXC4 and ISO 9001 certification. This means every part we deliver is manufactured under strict quality control, with full documentation and traceability.

Whether you need one-off prototypes or large batch production, our steel milling service is designed to scale with your requirements while maintaining consistent accuracy. By handling CNC milling alongside other in-house processes such as profile cutting and steel finishing, we provide a seamless supply chain with fewer delays and less complexity for your team.
