Pole sheets where mechanical strength meets magnetic stability

Engineered for extreme loads and continuous duty, our pole sheet electrical steels provide the mechanical robustness and magnetic stability your generators rely on.

High-load, long-duty generator robustness

Whether it’s a generator in a power plant or an industrial turbine, having confidence in the mechanical robustness of the motor at high rotational speeds is essential. Our range of hot and cold rolled pole sheet steels leads the way in supporting large rotating machines, where structure and stiffness are just as important as magnetic performance.

Meeting the demands of large rotating machines

Large rotating machines, such as hydro and turbo generators, require magnetic stability and mechanical strength under high loads and long duty cycles. Backed by proven expertise, our market-leading pole sheets deliver guaranteed mechanical and magnetic properties, providing a reliable balance between resistance to electromagnetic and centrifugal forces and strong DC magnetic performance for demanding generator applications.

Mechanical robustness

Designed to withstand high mechanical loads, both in static and dynamic conditions in large rotating machines.

Stable magnetic behaviour

Consistent DC magnetic properties support reliable generator performance over time.

Operational reliability

Classified according to their yield strength (EN 10265:1995), our hot and cold rolled grades are suitable for continuous operation and long service life applications.

Manufacturing suitability

Compatible with industrial processing and assembly requirements for large components.

Applications

Pole sheets are commonly used in:

Hydro power generators

To support efficient energy conversion through strong magnetic permeability and low losses and reduce maintenance requirements.

Turbo generators

To deliver energy conversion efficiencies and heat generation reductions at high rotational speeds and standard grid frequencies.

Large industrial rotating machines

To help maintain torque stability and consistent electrical output and provide the required robustness for high-mass, high-load rotor designs.

Power generation infrastructure

To support stable voltage output and efficient energy conversion by providing structural strength and dimensional stability to the rotor.
