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.
