Guangzhou/ ShenzhenThe silicon content of cold-rolled grain oriented silicon steel sheet is above 3.0%. The main purpose of cold-rolled grain-oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel. In order to meet different standard requirement, there are 3 main series in the market.
