At GNEE, we specialize in the supply of high-performance grain oriented electrical steel (GOES) tailored for transformer core manufacturers, power utilities, and electrical equipment producers worldwide. For overseas clients seeking reliable, low-loss core materials, we offer B20R070 (0.20mm), B23R080 (0.23mm), and B30R090 (0.30mm) Grain Oriented Electrical Steel – grades that deliver superior magnetic properties, consistent thickness tolerance, and excellent coating adhesion.
Whether you need to reduce no-load losses in distribution transformers or improve flux density in large power transformers, our team provides end-to-end support: from grade selection and sample testing to just-in-time delivery and after-sales technical assistance.
Key Performance Advantages of Our GOES Coils
- Low core loss – Reduces transformer no-load energy consumption by up to 30% compared to conventional CGO.
- High permeability – Enables smaller core cross-sections, saving copper and reducing overall transformer weight.
- Uniform coating – C5/C6 insulation coating ensures high interlayer resistance and excellent punching/stamping performance.
What's Silicon Steel?
Silicon steel, a specialized metal material, is renowned for its fine-tuned silicon content, which endows it with exceptional electromagnetic properties. Distinguished by their grain orientation, they are categorized into Grain-Oriented (GO) and Non-Oriented (NGO) electrical steel.
GO types, favored for their high magnetic permeability and low core loss, are particularly sought after in the manufacturing of transformers and motors. Conversely, NGO types, with their uniform magnetic properties, are ideal for various motor and transformer cores.
The production process of electrical steel, involving stringent chemical composition control, hot and cold rolling, annealing, and coating treatments, is pivotal to the final product's performance.
Exploration of Silicon Steel Applications in the New Energy Industry
- The application prospects for silicon steel in the new energy sector are vast, especially in the manufacturing of electric vehicles, where it serves as a core material for drive motors, directly impacting motor efficiency and vehicle performance.
- Additionally, in wind power generation, the manufacturing of large wind turbines relies on high-performance electrical steel.
- In energy storage systems, electrical steel plays a significant role in the inverters and transformers within battery storage systems, enhancing the efficiency and reliability of energy storage.
With the growing global reliance on renewable energy, the market demand for electrical steel is expected to continue rising. The future development of electrical steel will focus on increasing magnetic permeability, reducing losses, optimizing coating technology, and developing environmentally friendly materials.

What is grain-oriented electrical steel used for?
Grain-oriented electrical steel is used mainly as a core material for transformers, and its iron loss proper- ties have a large effect on transformer energy efficiency.
What is the difference between grain oriented and non grain oriented steel?
Non-grain-oriented electrical steel (NGOES) is mainly used in rotating equipment, for example, electric motors, generators and over frequency and high-frequency converters. Grain-oriented electrical steel (GOES), on the other hand, is used in static equipment such as transformers.
What is cold rolled grain oriented electrical steel in coils?
CRGO Slit Coils, also known as Cold Rolled Grain Oriented Steel Slit Coils, are electrical steel products that are widely used in the manufacturing of transformers, inductors, and other power electronic devices.
