Chemical Composition:

Manufacturing of Copper Clad/Coated Steel Strip 

We use sand paper to polish the surface of copper and steel. Then, mill imposes 130T pressure on the copper and steel to make them cohesive. Next step is the anneal procession, in which big annealing furnaces are applied. Finally, slitting machines slit large coils into the strips you want. 

Packaging of Copper Steel Composite Strip

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
