The top of the wall is installed with ordinary galvanized barbed rope for protection. Although the effect is better, the style is not beautiful. In recent years, it has been gradually replaced by blade barbed rope. First of all, the protection ability itself does not have any point of emphasis, can not use its own climbing at the same time, due to the relatively large volume of the intention to turn over the personnel caused no small difficulty, the whole body has a spike is very easy to be scratched or hook clothes, so in this aspect of the protection ability is better. Moreover, the style of spiral cross is more beautiful than the original single style, which is more suitable for some high-grade apartments and other external walls of the fence, at the same time, it will not cause the feeling of imprisonment in the interior.

During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
