Grain Oriented Electrical Steel

Stalprodukt S.A has been manufacturing cold rolled electrical steel for more than 30 years. We produce cold rolled grain oriented sheets (CRGO) called also transformer sheets. They are made from 3% silicon steel.

Four grades of CRGO sheets are produced in Stalprodukt:

  •  M3 (0.23 mm),
  •  M4 (0.27 mm),
  •  M5 (0.30 mm),
  •  M6 (0.35 mm).

We also produce toroidal cores coiled of transformer sheets.

 

In 2010 production of laser treated steel was launched in Stalprodukt.

The process of laser scratching allows for a significant, durable improvement of electrical steel strips magnetic parameters through the reduction of their core loss.
