Production capacity and equipment choice will be correspondingly customized as per real situation and need, from mini scale up to million ton level.

Cold rolling solutions
After hot rolling process, cold rolling process is requested if you still need the product to possess precise shapes and tolerances. Cold rolled steel typically has a better, more finished surface with better tolerances compared with hot rolled steel.

According to your material, there are the following cold rolling solutions for you to choose: stainless steel, carbon steel, copper and aluminum.

Stainless steel cold rolling
MET supplies the mature and reliable stainless steel cold rolling solutions for customers. Cold rolled stainless steel refers to the hot rolled stainless steel that has been subjected through extra processing to help improve both its mechanical and dimensional properties. In the cold rolling procedure, the cooled hot rolled stainless steel is passed through a set of rollers at room temperature. According to the application of cold rolled steel, additional processes and equipment will also be needed such as pickling, annealing, degreasing, leveling, galvanizing, color coating and so on.

Cold-rolled stainless steel can be easily molded into different shapes, making it a popular choice for many industrial applications. Despite cold rolled stainless steel strip process being quite costly and more labor intensive, it can achieve greater surface qualities and tighter dimensional tolerances.

Carbon steel cold rolling
MET supplies the customizing carbon steel cold rolling solutions for each client. Because of its excellent dimensional tolerance and press formability, cold rolled carbon steel is typically used in a wide range of structures and applications such as machinery framing, ductwork, construction, and other varieties of industrial applications.

Copper cold rolling
Besides steel cold rolling solutions, MET also involves the proved nonferrous metal cold rolling solutions, such as copper cold rolling and aluminum cold rolling. Copper cold rolling process involves reducing the thickness of the copper strip by passing it through a series of rollers. The resulting copper strip is thinner, stronger and more malleable.

The cold rolling process has several advantages for the copper strip, among which the most eminent is that it produces a higher-quality copper strip than other methods. The process improves the surface finish of the copper strip and produces uniform thickness. Another advantage of the cold rolling process is that it produces a stronger and more malleable copper strip. The cold rolled copper strip is more elastic and can withstand more stress without breaking.

Aluminum cold rolling
Aluminum cold rolling process is a kind of aluminum processing technology, which can process aluminum plates into products of various shapes and sizes. This process is widely used in construction, automobile, electronics, aerospace and other fields.

Since cold rolled aluminum is obtained by hot rolled aluminum after cold rolling, some surface finishing is performed in the cold rolling process. Therefore, the cold rolled aluminum plate is better than the hot rolled aluminum plate in surface quality (such as surface smoothness), and the formed appearance is also better. If there is a high requirement for the coating quality such as the subsequent lacquering of the product, it is recommended to select a cold rolled aluminum plate. In addition, the cold rolled aluminum plate usually has a slightly higher yield strength than the hot rolled aluminum plate, and the surface hardness is also higher, depending on the degree of annealing of the cold rolled aluminum.
