Preformed Windings engineering team

A Critical Partner for Energy Infrastructure

For over 50 years, we have helped energy companies, OEMs, and service organisations extend the life and improve the reliability of their most critical rotating machines.

Our Story

Built Around a Simple Belief

We believe that the organisations responsible for the world's energy infrastructure believe in quality and deserve a coil and bar manufacturing partner who understands the consequences of failure -- and engineers against it. That obsession with quality has guided everything we've done for over 50 years.

Today we operate from two facilities in Rotherham, South Yorkshire, serving OEMs, utilities, and independent service companies across every continent. As members of EASA , NHA , IHA and the AEMT , we are embedded in the global network of organisations responsible for keeping critical energy assets running.

Our expanded manufacturing capacity -- now 60% larger with a second facility opened in December 2024 -- reflects growing demand from customers who see us not as a coil and bar supplier, but as a critical manufacturing partner in extending the life and improving the reliability of their infrastructure.
