Cold rolled steel is steel produced by cold rolling. Cold rolling is to further thin the No. 1 steel plate to a target thickness under room temperature conditions. Compared with hot-rolled steel plates, cold-rolled steel plates have a more precise thickness, smooth and beautiful surface, and have various superior mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard and not suitable for processing, cold-rolled steel plates are usually required to be annealed, pickled and surface smooth before being handed over to customers. The maximum thickness of cold rolling is below 0.1--8.0MM. For example, the thickness of cold-rolled steel plates in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capabilities and market demand of each factory.

3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide,etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.
4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).
5.High-speed rolling and full-continuous rolling can be realized with high productivity.
