The grain oriented silicon steel coil is the basic raw material for manufacturing transformer cores. Its key feature is that the grains are highly oriented in the rolling direction. This gives it very high permeability and extremely low core loss along that direction. All our coils come from well-known domestic mills like Baowu and Ansteel. These mills have world-class silicon steel production lines. Their product quality is stable and reliable. We buy directly from the mills. This ensures all coils are genuine materials. We never add scrap or use substandard products. Our product is the foundation of quality.
Since our company was founded in 2000, we have built a complete management system for coil procurement, storage, and slitting. Transformer cores require materials with high consistency. We require that each supply batch has the same grade and thickness tolerance. When coils arrive, our quality inspectors check the thickness and surface condition. Only accepted materials enter our inventory and production. Our warehouse currently holds multiple grades and thicknesses of coils. This allows us to respond quickly to different orders. Our grain oriented silicon steel coil is handled with care.
Precision Slitting for Different Needs
The common thickness options for grain-oriented coils are 0.23mm, 0.27mm, and 0.30mm. Thinner materials give lower eddy current losses. However, they are more difficult to process. We have 4 slitting lines that can cut wide master coils into narrow coils at your specified width. The tolerance is kept very small. The slit narrow coils can be used directly on shearing lines for sheet cutting. They can also be supplied directly to clients who need pre-slit material. Our slitting equipment has disc cutters and tension control systems. This ensures smooth edges and consistent width. Our grain oriented silicon steel coil is slit with precision.
Flexible Supply for External Clients
In addition to using these coils for our own production, we also supply slit narrow coils and full master coils to external clients. Some clients have their own stamping or lamination production lines. They need to buy silicon steel coils in different widths. We can supply coils in various forms, from full master coils to pre-slit narrow coils. Whether you buy a full coil or a slit product, we maintain the same quality standard. You get genuine material, precise slitting, and proper packaging. Our grain oriented silicon steel coil is delivered in perfect condition.
