Package

The steel pipe can be bundled up, binned, bundled up with fat coating, or binned with fat coating and other customized package.

Compared with hot rolled type, the cold rolled seamless steel pipe is more precise on size. As its outer diameter can be as small as 5mm and its wall can be as thin as 2.5mm, our product is suitable for various situations to meet special requirements on high accuracy. At room temperature, this product is made of steel plate or steel band, which is processed in cold drawing, cold bending and other procedures. With the cold rolled technique, the product features great plastic deformation and its stress value at the yield point increases so that this product is endowed with high mechanical and processing properties. In addition, our cold rolled seamless steel pipe is shaped in large production quantity at high speed without damaging the coating. Made with various types of cross sections, the product can be used at different situations.
