As it was mentioned in the article about the types of profiles, the iron shield, like other iron profiles, is produced by hot rolling and cold rolling.

Hot rolling: This method, which is also known as the fabric method, first the steel ingot is heated and then rolled after reaching the desired temperature. During the rolling operation, its thickness decreases and its length increases. Finally, by passing through the middle and end rollers, it becomes a shield and then it is cut into desired dimensions with cutting devices. Chopped and small pieces of shield are called bite. The quality of the profile in terms of dimensions of the shield produced by the hot rolling method is better than the cold rolling method. Because the technology and devices used in the hot rolling method are more advanced. Cold rolling: In the cold rolling or pressing method, the section of the beam is divided into two parts in the middle, and in this way a shield is produced. This method of shield production is not very common and in cases where it is not possible to use the hot rolling method, this method is used.
