The raw materials and auxiliary materials of our 50W800 non oriented silicon steel are mainly imported from South Korea and produced using South Korea’s advanced technology.
The quality has been recognized by Chinese users and has been widely praised in countries and regions such as the United States, Japan and Europe.
Non oriented silicon steel coil containing 1.0 to 4.5% of silicon and less than 0.08% of carbon is called silicon steel.50W800 non oriented silicon steel coil has the characteristics of high magnetic permeability, low coercive force, and large resistivity.It is mainly used in motors, transformers, electrical appliances, and electrical instruments. So it is also called Electrical steel.

Our non-oriented electrical steel is widely used in electric motors, transformers, and precision machinery for its excellent magnetic properties and energy efficiency.




Our streamlined process runs from incoming-inspection, precision feeding, high-grade welding, controlled annealing, uniform coating & drying, to secure packaging—every step engineered for consistent quality and traceability.


Factory certificates & Product Test
To guarantee benchmark quality, every coil undergoes our “inspect-and-retain” protocol:
• Individual samples are taken from each coil and rigorously tested for corrosion resistance, elongation/yield strength, magnetic flux density, core loss, hardness, insulation resistance, and lamination factor—only coils passing all criteria are released.
• Each retained sample is sealed by coil ID and archived for full traceability.
• A digital dossier is created for every coil; scanning its QR code instantly reveals original test data, production batch, and process parameters—true “one coil, one code, lifetime traceability.”

Trust by foreign customers
With over 10 years of export experience, we have delivered thousands of tons to customers in more than 20 countries and earned widespread acclaim.
