Store kornorienterede elektriske plader fremstilles af varmtvalsede bredbånd af siliciumlegeret stål af forskellig tykkelse, hvis kornstruktur er blevet ensrettet for at opnå en høj magnetisk ledeevne. ###>GOES are produced from hot-rolled coils of silicon alloyed steel of different thicknesses of which the grain structure is uniformly directed in order to allow for magnetic conductivity with a high degree of efficiency.
