Shanghai Guan You Industrial Co., Ltd. primarily deals in non-oriented and oriented silicon steel. It also handles silicon steel products from Baosteel and Wuhan Steel. The products are widely used in various industries such as automotive motors, electric motors, welding machines, power transformers, reactors, instrument transformers, and many others. The company can also handle futures business for designated steel mills on behalf of customers.

The company is equipped with multiple Taiwan-made silicon steel slitting and shearing equipment to ensure precise processing dimensions. It offers two categories: regular material and self-adhesive.

0.2 Self-Adhesive Series: B20A250-Z Cold-Rolled Non-Oriented Silicon Steel Performance:

The requirements for silicon steel performance mainly include:

1. Low iron loss, which is the most important indicator of silicon steel sheet quality. Grades are classified based on iron loss values in various countries; the lower the iron loss, the higher the grade.

2. High magnetic induction intensity (magnetic flux density) under strong magnetic fields, which reduces the volume and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, insulating materials, etc.

3. Smooth and flat surface with uniform thickness, improving the filling factor of the core.

4. Good punching performance, which is particularly important for manufacturing micro and small motors.

5. Good adhesion and weldability of the surface insulation film, providing corrosion resistance and improving punching performance.
