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.
