Cold rolled special steel strip

We are manufacturing the cold rolled special steel strip products with a good variety of materials and thickness according to your use. We achieved products of high-precision thickness, using rolling mills equipped with a rolling control system(FF AGC；Feed Forward Auto Gauge Control system) and andperipheral technology. [ex. 0.5+-0.005mm] We will supply you the best material to correspond to the various uses.
