1) Available upon demand.
2) Other nominal thicknesses and mechanical properties on request.

Cold rolled pole sheet is classified into grades according to yield strength. In addition, minimum values are defined for tensile strength, elongation and magnetic polarization at a field strength of 5,000 and 15,000 A/m.

1) Other nominal thicknesses on request.

Thanks to specially selected starting materials and specialized manufacturing technology we can guarantee minimum values for our pole sheet grades which easily exceed those defined in the standards.
